I picked up my new Glock 21 gen 4 on 8/11/23 what a beautiful piece of craftsmanship! The slide is stamped “USA” not AuAustria. Which is great! Im prior military so USA fits the bill! Gen 4 is getting harder to find, the new double spring recoil is great! New texturing on the hand grip is a welcome update from the gen 3. The keeping with the finger grooves gen 4 is nice, your hand stays in place! The gen 5 they are deleted! The gen 4 shoots spot on! Readjusting the sights wasn’t needed! Thank you grabagun for smooth buying process!

Excellent gun. Handles the recoil much better than a standard 1911 and the 13 rd capacity is great. Highly recommend.

Simple , Always works , part’s are sold everywhere . The G 21 is exactly what you think it will be . 45 that always hits the target if your skill allows it too . good weapon and arguably good caliber

Glock…The revolver of the semi auto pistols. The KISS ( Keep It Simple Sam ) method of operation is my kind of tool , in the big bore down to the smaller calibers… And yes … Glock frames are virtually the same 2day as some times pass… but hey… how many ways can you make the wheel better… even the most expensive fighter jets still use basic rou...Read More Read more about review stating Glock … THE REVOLVER OF THE SEMI AUTO PISTOLS

Definitely what I wanted and I expected! Haven’t shot it yet, but I am absolutely in love with it. Surprised that it came with 3 magazines and a beaver back which was great and unexpected!

Its one of the most reliable Glock models ever made, it eats any ammo, it never fails to feed, and is so simple to tear down, clean, and operate, that’s why it’s one of the best! Easiest process to purchase, it won’t be my last gun from guns.com.
