Been in the market for a while and finally decided to buy from F1firearms. I was comparing this against similar products from the other site and decided to take the chance. Glad I did. Arrived in 5 days, well-packaged, and the quality speaks for itself. Installed it on my Glock 45 and ran 355 rounds through it without a single hiccup. This is the real deal.

Arrived in 2 days, well-packaged, and the quality speaks for itself. Installed it on my G19 Gen3 and ran 258 rounds through it without a single hiccup. This is the real deal.
