Why This Wins
Having built dozens of P80s on our Spring TX CNC floor, this frame hits the sweet spot between price and performance. The reinforced polymer stands up to .45ACP recoil better than budget options, without paying for features most builders won’t use. We ship these with all necessary jigs – no hunting for parts.

Fit my Glock 17 perfectly. No issues.
Diana L. (verified owner) –
Exactly what I needed. Fast shipping too.
Christina M. (verified owner) –
Bought this as part of a larger build project. F1firearms had the best price by a decent margin and shipping was fast. The Glock polymer 80 frame glock 19 – 45acp itself is well-made — Tight tolerances. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
Amanda C. (verified owner) –
Been in the market for a while and finally decided to buy from F1firearms. I was comparing this against similar products from a local shop 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 G17 Gen4 and ran 391 rounds through it without a single hiccup. This is the real deal.
Danielle P. (verified owner) –
Better than what I got from a local shop last time.
Josh F. (verified owner) –
This is my go-to store now. Third order, third time everything shows up fast and in perfect shape. Keep it up.
