Got this for my G23 build. Quality is solid, finish is clean, and it fit without any modification. Already planning my next order.

Been in the market for a while and finally decided to buy from F1firearms. I was comparing this against similar products from another online store 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 17 and ran 312 rounds through it without a single hiccup. This is the real deal.
