(5 out of 5) Very pleased
by DR from South, AL on June 22, 2018

The one I received is in great shape with minor holster wear. It came with the box, 2 magazines, Glock factory night sights, and backstraps.

(5 out of 5) Amazing Quality
by Adan from Kearneysville, WV on June 5, 2024

I admit that I was quite skeptical in purchasing a second hand gun from a law enforcement agency, but the well taken photos made me pull the trigger. My pistol arrived within 4 business days and upon initial inspection I’d bet an entire paycheck the gun hasn’t had 100 rounds run through it. The internals were factory clean, the barrel, slide, and recoil spring contained minimal powder residue and the slide finish was in nearly mint condition. 

I give credit where it’s due and Sportsman's Outdoor Superstore sent a gun I would deem “excellent” condition for my first ever purchase.

(5 out of 5) Glock 21
by Gary from Randleman, NC on July 3, 2024

Just received the Glock 21 Gen4 I ordered, took 4 days. I am very satisfied with my purchase. I would definitely recommend SOSS if you are looking for a firearm at a good price.
