Item was as described and fit perfectly. The stainless steel finish was nice and thread protector was a perfect match. Easy to install and use. Very happy with product so far. Price was fair for item when compared with similar products.

Glock 21 threaded barrel

by TXLEO, from TX, United States Written on August 12, 2024
This item appeared to be new old stock. That being said the barrel installed identically to OEM and the threaded portion functioned exactly as expected. Minor inconvenience with the order not being able to ship to a PO Box even though that's the way the order was placed without issue.

Nice barrel

by Big Mike, Verified Owner from KY, United States Written on August 10, 2024
I put this barrel in a Rockslide brand slide on a Polymer80 frame that I recently finished. The groups are good. I’m quite pleased with the barrel.
