The Smith and Wesson SD9 is a handsome pistol that is a worthy competitor in the polymer pistol arena


The Smith and Wesson SD series of pistols can trace its lineage back to the Smith and Wesson Sigma of the early nineties. Back then, S&W was still innovative and was trying to snag some of the market share that was (and is) dominated by Glock. The Sigma was an unattractive pistol that was chambered in both 9mm and 40 S&W, but it seemed to work. The Sigma did have a few LEO contracts based on the proven and past successes of S&W third gen autos and revolvers, but they were soon phased out very quickly in favor of the more enigmatic Austrian pistol.

There were a few legal hassles at first because of the Sigma similarity to the Glock series of pistol, but that doesn’t concern us here. Suffice it to say S&W changed directions with their marketing campaign and the Sigma became the budget-friendly polymer alternative. The Sigma was updated in 2011 with a facelift and the newer and more handsome iterations were coined the SD9 or SD40 depending on chambering.

The SD9 I am reviewing is one of a set of three trainer pistols that we use for our classes in our shop. Out of all the pistols I have ever had trigger time on, I can say that I have the most experience with this particular type.

This is not a pistol I would call a favorite, as a matter of fact, it has some things that I down right dislike in a pistol, but due to our classes, we use them quite a bit. Are they perfect? No, by no means. But they do work. They are accurate enough, and reliable to boot. In some of our classes (depending on the size) we can expend close to 2000 rounds of 9mm in an afternoon between the three of them. I have used them in the pouring rain, the freezing cold, and humid summer. They have been dropped in mud, and snow, and covered in rain water and continued to shoot.

We have had two cases of serious malfunction, both on the same pistol besides basic stovepipes due to “limp wrist” with expended rounds where the pistol would not go into battery, but the slide would not open either. We ended up inserting a dowel into the barrel and sharply beating the case out of the chamber. This was no fault of the pistol but was due, we found to some Winchester factory ammo brass being too long and causing excessive headspace and swelling in the chamber. After a quick once over and a shot of oil in the breech, she ran without a hiccup.

As a warning, you are going to see a lot of comparison to the Glock pistol in the overview. This is not a Glock vs SD9 article, it is simply to help put in perspective some of the features of this pistol. There, I said it.



The SD9 has a two tone finish that makes for a handsome pistol. The grips have different levels of texturing for a more firm gripping surface. The slide has both front and rear serrations that are supposed to assist with racking the slide but the slide serrations, are in my mind, poorly designed. The SD9 comes in at 23 oz, has a 4 inch barrel, and overall is very similar in size and heft to the Glock 19. There is no external safety on the SD9. The trigger, like a Glock, has a trigger safety that is deactivated once the shooter begins to pull the trigger. The trigger weight is a different story. Most Glocks have between 4.5 to 6lb factory triggers. The Smith and Wesson website says the trigger pull on the SD 9 is roughly

The author prefers the three dot sights to the Glock stock sights. However,The SD9 sports a slightly higher bore axis, which increases muzzle flip

8 lbs, and I don’t doubt that. My scale shows an average of 7.75 lbs pull weight between all three of our trainer pistols. That’s a little too heavy for me.


It comes with two 16rd magazines, for those of us who live in God’s Country. The barrel sports a loaded chamber indicator. The fixed three dot sights, are in my opinion better than the dot-in box sights that most Glocks sport, but that is simply my preference. An interesting feature of the SD9 is the textured pad on either side of the frame for placing your trigger finger when not firing.

The one big advantage the SD9 has over the Glock, in my opinion, is the grip contour and angle. In my experience and opinion the SD is a much more comfortable and ergonomic pistol to shoot and carry auto pistols. Also, from what I have seen, new shooters tend to shoot the SD9s better than Glocks. Some people may cry foul on that remark, but oh well.

Disassembly is identical to the Glock. You remove the magazine, ensure the chamber is

unloaded, pull the trigger, pull the slide back about a quarter inch, and pull down on the two locking tabs on either side of the frame and run the slide forward off the rails. Reassemble by running the slide back on the frame rails all the way. Easy peasy.



On the Range

Accuracy with the SD9 is tolerable in most cases and very decent in some. I have difficulty with the triggers on these pistols as they stack considerably, have a smooth face, and are too heavy for my taste. They are also hinged which, unlike a Glock trigger face, tends to pull the whole pistol barrel down and rounds to impact low. Trigger reset point is also much further out than I like for it to be. However if a shooter takes their time and executes a clean trigger pull, they will hit what they are aiming at.

Off a bench, I tried four different types of ammo: some 115 full metal jacket handloads, Blazer Target steel case 115 gr, Winchester 9mm NATO 124 grain, and Hornady Critical Duty 135gr. I found that it shoots to point of aim at 25 yards with most 3 shot groups in the 3-4″ range.


A good example of typical accuracy with the SD9. Not bad, but nothing to write home about.

The worst groups were with the handloads at about 5″. The best groups came consistently from the Blazer with the smallest group coming in at 2 3/4″. The fixed three dot sights are large and very easy pick up. I had no trouble seeing them and focusing on the front sight for rapid pairs at 7 and 15 yards.




The Smith and Wesson SD9 is a fine pistol for target practice, self defense, and teaching a new shooter the basics of semi-auto pistol operation. They are comfortable to shoot, have combat-accuracy, and most importantly they are reliable.

The biggest reason we chose these pistols for our classes instead of comparable brands is because of price($389 MSRP, $300 street price), and reputation of the company. They are almost half the cost of Glock and can do just about everything a Glock can. The design has been around for roughly twenty years, and Smith and Wesson keep producing them, so there must be some merit to this budget friendly auto-loader. Do I carry one? No. Would I? Yeah, sure.

Glock 40 M.O.S.


The Glock 40 M.O.S. is a newest offering by Glock to hit the shelves. Chambered in the powerful 10mm and outfitted with the Modular Optics System, there is little this behemoth can’t do.

This is a review that I have been very anxious to bring to ya’ll. It has been in the works for some time now, and to finally have it ready is exciting. I finally got my hands on a Glock 40 M.O.S. in 10mm Auto for reviewing purposes.

The Glock 40 M.O.S. was the prom queen at the 2015 SHOT show convention in Las Vegas. It was known that Glock was going to unveil an optics mounting system on their pistols in a bid to compete with other manufacturers, but it was thought by those in the know that it would be only be on the tactical/practical/ competition pistols, e.g. Glock 34, 35, 41, etc. That all did come to pass, but what surprised the gun industry was that enormous long-slide black pistol in 10mm Auto with the same optics mounting system. Enter the Glock 40 M.O.S.

The Glock 40 M.O.S. is essentially, with a few differences, the classic Glock 20 Gen 4 save for a 6”barrel and slide. The M.O.S. (which stands for Modular Optics System) is a removable plate system on the slide just in front of the rear sight. The pistol comes with a blister pack of four different plates that when attached to the pistol slide, allow the mounting of the shooter’s preferred optic, e.g C-More, Trijicon, Leupold, etc.

The pistol, which is too big for an IDPA box, is geared toward the hunting market. The 10mm is not really a feasible plinking and competition round (unless you are bloody rich and a glutton for punishment), and has found a niche in the backwoodsmen and hunters who like the hot rod performance and high capacity the 10mm offers. For years, the Glock 20, with its service length 4.6” barrel has worked fine.


Here you can easily see the plate mounting system on the slide secured by two allen head screws. The classic Glock adjustable rear sight is also plainly seen.

However, in some states a 6” barrel is required to hunt big game with a pistol. Glock has sold an aftermarket 10mm 6” barrel for their models 20 and 29 for years, but it looked kinda goofy with that extra inch and half or two sticking out from the end of the slide of a service size Glock 20. The added velocity from the 6” barrel was noticeable, but you were stuck with the same stock sight radius. The Glock 40 fixes that issue, and then some.


Upon opening the box, I could see that Glock is really an expert at space saving. That little plastic box was crammed with that big pistol, three magazines, a mag loader, cleaning brush, sight adjusting tool, gun lock, 4 additional back straps and beavertails, extraneous paperwork, and owner’s manual. Once I took everything out, I couldn’t close the box again so I had to repack it with just the essentials. Since this pistol is so new on the market, (they just started shipping in August, and there is a huge backorder) there really isn’t much in the way for holsters. I found that just about anything that will fit a Glock 20 will fit the Glock 40, as long as you don’t mind that barrel poking out past the end.


The pistol comes crammed into a neat plastic box with a ton of accessories.

The pistol, despite the size, is rather lightweight and very well balanced. Unloaded weight is 28 ounces, and with a loaded 15rd magazine is roughly 41 ounces, or about the weight of an unloaded 1911 Gov’t. I figure that big pistol would be nose heavy, but it actually points just fine. The long slide and barrel also serve to help control muzzle flip, but we will get to that part soon. The pistol has adjustable Glock sights, which I specifically requested. They are a plain and unassuming affair, mirroring the whole pistol in styling and function.

The grip is quite a doozy. I have average sized hands, I would say. Getting a grip around the Glock 40 is very trying. I am also, admittedly a 1911/HiPower fan boy, so the Glock grip angle is very foreign to me. I have to use all of my hand to really get a good grip in order to control it during shooting. There are 15 of those long 10mm bad boys in the mag and as such, it creates a very large grip. The 4 replaceable back straps and beavertails are going to be, at least in my version, unusable, because all they do is make the large grip even larger.

The slide release, is in typical Glock fashion, very small and difficult to release. I have long since trained myself to “slingshot” a pistol slide when loading and shooting, so it doesn’t bother me much, but I can see where it would be a issue for other shooters.

The trigger is, in my opinion, a refined version of their standard trigger. Glock makes no mention of it in any literature as being any different than the 5.5lb trigger on any of their other pistols, but it feels so much smoother to me. The take up is standard, until you feel a slight bit of tension. Upon applying a few pounds of pressure the trigger will release. The reset is absolutely gorgeous and is mere millimeters from the breaking point. All you have to do is let your finger out a scoche and the very discernable click of the trigger resetting is heard. Rinse, repeat.

Field stripping the Glock is the same as it is with any other Glock. Ensure the pistol is unloaded, drop the magazine, check again to make sure it is unloaded. Pull the slide back an smidge while pulling down on the two tabs on either side of the frame and then rack the slide forward. With the slide off, simply remove the mainspring and barrel. Reassembly is even easier. Put the slide/barrel/spring back together, and let the whole assembly sit on the slide rails, and then just slide the whole thing back on. No tabs, no pulling, twisting. Bada bing, bada boom. Speaking of boom…

On the Range

The place where this pistol really shines is the range. I have plans to take it on the 100 yard rifle zero range, but for now we will see how she does on the standard 25 yard pistol range. Recoil is stout, it is not as sharp as 45ACP+P loads, but there is a lot of muzzle flip and torqueing in the grip. The ammo I used was American Eagle, RAM Precision, and the brand new SIG Elite Performance. All ammo was 180 grain full metal jacket, except for one box of the RAM which was 150 grain hollow point.


This sub inch grouping shows the inherent accuracy of the pistol and cartridge. The black dot served as an aiming reference.

The American Eagle was junk, plain and simple. It was loaded to .40 S&W levels and wasn’t very accurate. It produced about 4.5” groups, but I didn’t really measure them. The RAM Precision 180 grain FMJ was printing groups half that size. But again I wasn’t overly impressed. The RAM 150 gr HP and the SIG 180gr FMJ is where the money was made. I was able to produce two groups each with both types of ammo that grouped at or under an inch. Yes. You read that right. 3 shot groups at 25 yards under an inch. I thought it was a fluke the first time, until I did it three more times.

Now, I am not some wiz-bang wünderkind shot. Neither am I lying or exaggerating. I don’t get anything extra for being dishonest. I simply focused on the front sight, calmed my breathing and executed a good trigger squeeze. Upon taking up a good Weaver stance and engaging in rapid fire at 25 yards it was very easy to keep all 15 of those big pills in the 9 ring of a B-27 target.

As for longer barrel = higher velocity, I was getting about 5-6 percent higher velocity than was advertised. So, for the SIG Elite Performance ammo, which was advertised at 1250 fps and 624 ft lbs of energy, I was getting readings on my chronograph in the ~1315 fps and 690 ft lbs range. That is, in my opinion, a substantial gain that equates well to the person who buys this for hunting or backpacking. I am still looking for some hot, heavy Underwood ammo to run through it, but until then, the SIG ammo works just fine.

As for the optics situation, I have never had optics on a handgun, and I am not sure I wanna fork over several hundred more dollars for a sight that I may not like. It shoots and handles great without one so far, so I think I will leave the slide and rails free of impediment.


I am beyond pleased with this pistol. It is fun to shoot, accurate, always draws a crowd every time you touch off a boomer, and elicits a smile from everyone that shoots it. This is a very accurate, safe, and easy to use pistol. This pistol is perfect for those wishing to hut deer or pig sized game, or even as protection in bear country. With 15 rounds of hot 10mm and 30 more in the other two mags, a person could be a lot worse off. The Glock 40 M.O.S. may not be for everyone, but it works good enough for me. I may have to add the other 10mm Glocks to the stable just so big brother doesn’t feel so lonely…
