There are many great handguns on the market today, however; GLOCK is the benchmark in which all others attempt to reach. GLOCK pistols are revered for their simplicity, accuracy, and rugged reliability. Rightfully so given the fact that since 1982 GLOCK has been providing their Safe Action pistols to military, law enforcement, and civilian shooters all over the world.

The GLOCK 21 was designed to bridge the gap between power and capacity. The GEN4 features a modular back strap that allows for a custom grip to fit the individual shooter. The newly engineered frame utilizes rough textured technology to provide supreme ergonomics and a sure grip. The GEN4 recoil system has been enhanced to bring a longer service life to the Glock platform. Equipped with an oversized and reversible magazine release, the GLOCK 21 GEN4 is the pinnacle of performance. Pick up a Glock today and you will see that there is no substitute for perfection.

"Well, let me first say I am not a \"Glock Lover\". I purchased 3 generation 3 pistols last year (19,20, and 23). Found them ugly as a brick but some of the most functional and easy to shoot guns I own. The G21 was always too fat for my hand. The G20 I purchased was an SF (Slim Frame) and I went looking for a G21SF Gen 3...then I stumbled on this NEW Gen4 G21 on CTD for a VERY good price. As always, CTD had the gun to my FFL in 2 days. Took it straight to range bypassing my usual CLA I do on new guns and put 200 rounds of 230gr Military Ball through it. What can I say..it's a Glock. Not a FTE or FTF in all 200 rounds. Took it home, cleaned it, loaded it, and now it is my primary open carry weapon. If you know what Glocks bring to the table then there is no surprise here. Glocks are the \"Mack Trucks\" of pistols...big, ugly, no finesse..but they just deliver. I do plan on switching the front site for a fiber optic one (do that on all my pistols...like the contrast) whenever I get around to it. Very happy with it, with the price (CTD!!) and the delivery (CTD!!). It's not a Colt Gold Cup...then again...you could almost buy three of them for what one of those cost!If you have been hesitating over the Glock G21 Generation 4...don't wait till the price goes up (these are $40-$80 more elsewhere)."
