45 Cal Glocks - Of all the .45 semi-automatic handgun options, the Glock certainly has a place of honor. Glock is known for its reliability and simple design - an important factor for many shooters. The Glock is able to mediate between those who want a bigger weapon in a handgun and those who are tired of only carrying 6 or 7 rounds in a magazine. This brings us to the weapon we are looking for in this review, the Glock 21.
Glock introduced the G21 SF (Short Frame) in 2007 to compete for DOD contracts. The deal was not finalized, but the weapon's unique features attracted the interest of law enforcement agencies and civilians alike. Based on the 3rd generation Glock 21, the company made several changes to this version. We sold and serviced a Glock 21 SF for this Glock 21 review.

Of the changes to the Glock 21 SF, the most notable (by name) is the smaller rim round. Not to be confused with the frame size, the shorter frame provides less depth of frame than the 3rd generation version of the Glock 21. This short frame depth allows for a good grip and features for those with small hands. The latest generation (Gen 4) Glock 21 has the same grip length as the G21 SF.

As mentioned earlier, the Glock 21 SF is chambered in one of the "big boy" calibers - .45 ACP. Most shooters recognize the 45 ACP as the classic caliber, and many self-defense shooters still rely on the cartridge to this day.
Glock combines tradition with strength in the Glock 21 SF. The Glock 21 SF offers 13+1 power, which is a reasonable number considering the size of the frame.
Another unique feature of the Glock 21 SF is the inclusion of an ambidextrous magazine option. Although this feature is simple, I think it lacks functionality. I will talk more about this in the review. We chose to mount the Glock 21 SF scope with a Picatinny style rail for the accessory - there aren't many here and holstering is a concern.
Most versions of the Glock 21 SF available today come from police departments that have exempted them from service use. These deals can be found for as little as $350-$400 in some places – which is undoubtedly amazing.

When I first got my hands on the G21, I felt right at home with it. I know not everyone likes or even enjoys the Glock "experience", but as someone who owns and operates Glocks, I find it enjoyable. Some might argue that the Glock is an "acquired" taste - whether you like the ergonomics of the Glock or not, you'll love the 21 SF.
Even though it's designed for people with different hand sizes, the bezel still has a nice feel to it. I shoot the Glock 17 quite often and this scope offers a better grip than the 17. While I don't mind the feel or size of the frame, I still have some issues with the magazine version. I'll talk more about this later when I talk about work.
My expectations of how this gun would handle recoil and overall performance were wrong. Depending on the caliber, expect more problems on subsequent shots. However, I am very interested. This gun works very well in my experience. The gun handled every type of weapon I had without issue. I was very impressed with the return management.

Although the frame is comfortable, I wish it had a more textured surface. Even after shooting or sweating for a while, the G21 SF starts to feel. The slide on the 21 SF felt lacks front serrations and seems difficult to grip consistently. Some frame cutting and slide work would be a nice addition to the market.

The G21 SF rifle puts a lot of confidence in the hand - confidence increases when you realize that the next shot can be made quickly and accurately. I did a few drills using the zone C metal plate at 15 yards while moving forward and out. The precision strike and control I experienced with the Glock 21 makes the pistol a lot of fun to shoot.
Glocks aren't exactly known for fancy factory sights or triggers. They usually get the job done, and it's no wonder. My experience with the G21 SF matches any other Glock I've sold in the past.
The white "U" shaped rear sight with front post standard can be seen here on the G21 SF. I managed to make these looks nice enough to feel confident about, but I've reused them before. If you buy one of these G21 SFs (it's a cop sale) be prepared to swap out the sights for low light use. I know it comes down to preference, but a fiber optic front with a black backlight seems to work well for me.
Testing my G21 SF trigger using a Lyman trigger gauge showed an average pull weight of 5.5 pounds, which is pretty typical for a Glock trigger. I know there are a lot of people who are really against the causes. I've sold enough Glock pistols to not bother them too much.

The trigger feels smoother than a typical Glock trigger. This may be due to your age and years of "laundry". Regardless, I appreciate the smooth reception and crisp breaks. No real complaints from me here.
For the most part, guns are simple and straightforward. It is a Glock after all. I also noticed a few things about the rather annoying features - the original version of the double-sided magazine. I think Glock missed the mark here with the DOD contract requirements.
The magazine release design provides a much smaller area than the regular Glock magazine release. I had to break the handle and rotate the frame to access this version. My hands are on the average side of the scale. I'm a little surprised that I went out of my way to keep track of the magazine changes.

The slide show also taught me a bit of a lesson. The design seems to be on par with the regular Glock slide, but it doesn't seem to work as well. It takes incredible and precise pressure to move the slide. I ended up manually filtering the sliders for most of my shots.

This may not be a deal breaker (and I know there are aftermarket slide versions) but I think it's worth mentioning.
I used a Labrador doppler radar to collect ballistics data for the Glock 21 SF test range. Use Speer Gold Dot 230 gr. weapon, I shot 5 times with that Labrador.
The average muzzle velocity in this test was 832 feet per minute from the G21 SF. Speer advertises a velocity of 890 feet per second. Read more about bullet performance with the Glock 21.
The Glock 21 SF is a weapon proven and tested over many years of use. With Glock available and with aftermarket warranties, it's hard to go wrong with a firearm like this. Considering the price tag and the ability to find many used versions in good condition, the price seems high.
Glock 45 1000 Round Review
My experience with the G21SF exceeded my expectations at work and I now want it. It's not a perfect pistol, but I think it could be perfected with a few simple stock modifications. If you are looking for a well made and reliable .45 auto, the Glock 21 SF is for you. So I started researching my first firearm with the Springfield XD service model. But when I come to Gunstore, I see a lot of options. I got my hands on the OD Gen 3 G21 and I'm in love but haven't bought it yet. Although my first gun (in the first signature of the three, the other two being the G17 and G22 gen 3) is an old sf non-gen3 and is the way to go home in black. A quick dry shake made me like the tungsten guide rod and at the time confirmed that Sig didn't offer enough or cheap enough. 2.5k seconds later, it's still my favorite gun, maybe my favorite gun. For me it's easy to do, no zoom or any of the other models below, I chose the Glock and continue to prefer it. The tungsten rod balances the light magazine load and keeps my exercises consistent.
For me, it's not the best. Glock 21 I think
