Description
Product Overview
The Glock 21 Gen4 is a full-size semi-automatic pistol chambered in .45 ACP. Its 4.60-inch barrel, polymer frame, and Gen4 rough-textured grip provide a stable, controllable platform, while the Modular Back Strap System allows the grip circumference to be tailored to the shooter. The dual recoil spring assembly helps reduce felt recoil and extend service life. A reversible magazine catch supports right- or left-handed operation, and the fixed Glock sights offer a durable, familiar sight picture.

Bought this .45ACP...
Bought this .45ACP knowing nothing about the MOS Model. It was my intention of putting a holographic sight to do target shooting. Well this is what ignorance and not knowing about the availability of what is new and on the market. Oh, well now I have a new plinker that I can put a laser / light for better sighting of pistol. But this is just my opinion. This Glock 21 is working well as expected. The only possible flaw is the space between the slide and the frame. I can see through and I believe the space is too big. Hope the slide doesn't fly off when I fire it but we'll see. Other than this it shoots as accurate as expected. Love this handgun but need to find out about the spacing. Bud's did great job in shipping this to my FFL but prior to this had some issues with FFL license on file. We cleared it and it shipped expeditiously. Bottom line is check out if what you want is available before making a purchase of what is for sale.

The Glock 21 in Gen4...
The Glock 21 in Gen4 is quite possibly the perfect carry .45 acp handgun. It is considerably lighter than either a full size 1911 or a Commander, and it holds more ammo than either. While it is somewhat bulky and somewhat overbuilt, this isn't necessarily a drawback. The G21 is one of the smoothest shooting .45s I have ever owned, and is considered to be one of the lightest recoiling .45s on the market. And, it can take a steady dose of p ammo without a problem. Also, I have carried G21 Gen4 in a Galco Nano holster and a Jackass Rig, and find that it is surprisingly comfortable. If you have average size hands, gripping the 21 is more than just satisfactory. In short, the G21 in Gen4 may well be the perfect carry choice in the king of all defensive calibers - the .45. Try one. I don't think that you will be disappointed.
