Glock 21 Complete Specs and Full Gun Specifications

Remarkable for its accuracy and light recoil, the GLOCK 21SF delivers the legendary stopping power of the .45 AUTO round with 10/13 round magazine capacity. Countless law enforcement units swear by the G21SF pistol, and that's why this powerful, lightweight, all climate workhorse is standard issue from the North to South Poles. The SF model reduces the circumference of the receiver at the rear, or "back strap," offering increased comfort and controlespecially for shooters with smaller hands.

As good a shooter as any on the market. Had glock had a factory, assembly plant in the USA . In 1984, our military would be armed with a glock. My issue 1911. Was a great weapon. But rattled like a b.b. in a Pop can. I can hit playing cards consistantly a

I've had for many years a gen 2 glock 21 and carry it daily for duty. My hands are medium size and with Talon grips on the 21 it fits like a glove. My qual scores are typically 178/180 out of 180 which really boosts confidence. My life depends on my old p

The ugly black pistol. No thrills to look at but a sewing machine on the firing line. When your life depends on a weapon you want a Glock 21 on your side. It will do what it was designed to do, fire every time. I changed out the barrel to a stanless that

I've shot this model plenty of times and I feel in love with it on the first try its easy to control easy to clean and its very simple unlike the 1911 its very light and you can not go wrong with 13+1 in 45 ACP even though you're just going to need one sh

After I acquired a G26 I read some nice things about the G21 so I popped for one. As .45s go it isn't very expensive to buy at all. Since I already had figured out how to shoot my first Glock this one was right on the money the first time I shot it. I hav

What can I say? It's a Glock. It fires perfectly with almost no up keep. The SF frame fits nicely in my hands. Only gripe about the weapon is that it only came with 2 magazines. My gen 3 Glock 22 RTF 2 came with 3 magazines. I ordered the 3rd mag on my ow

Love each and every Glock I own! With that said, was a little diappointed when this arrived with several small scratches on top of the slide from what appears to be from the cleaning brush rubbing the slide while in the box.

As one of the other reviews noted, it's a big ole' Glock, what's not to like??? The order process was a little slow because I paid via E-check, but it was definitely worth the extra wait time. As for the G21SF, it arrived at my FFL free of scratches or bl

By far the best carry pistol in production. As a Smith Im asked quite often what Someone should get their wife or what someone to get for themselves and I always tell them Glock because it always goes bang no matter what. And don't alter it in anyway just

The Glock 21sf gets five of five stars. The weapon is typical Glock, that is to say, there is nothing to radically new with the SF designation. It is slightly easier to hold if you have medium hands. If you have small hands, I would look elsewhere, large
