(5 out of 5) Mine was as good as new
by Ron from Blytheville, AR on June 16, 2025

I figured that it would have holster wear and signs of shooting, but when it came in, it was like a brand-new pistol... no holster wear, perfect rifling, looked fantastic. I broke it down to clean it before shooting, and I couldn't get a speck of dirt off the components. I oiled it up, took it out to my personal range, and ran about 100 rounds through it just to get the feel for it... it shot PERFECTLY. I've never been a fan of Glocks, don't like the way they feel in my hand, but this was WELL worth the money. I can't say that all of the trade-ins would be in this condition, but this one looks like whoever owned it before me never carried or shot it... even the case and accessories were in new condition. As usual, SOSS shipped fast, was well below what I'd paid for it around here—even after the transfer fee from my dealer—and great quality. Thanks guys... appreciate you.
