Why the Glock 45 Gen 6 MOS Stands Out
The Glock 45 Gen 6 MOS combines the compact frame of the Glock 19 with the full-size slide of the Glock 17, offering a balanced feel for both concealed carry and range use. Its MOS system makes it adaptable for red dot sights, enhancing accuracy and versatility.

Packaging was a bit banged up when it arrived but the product inside was fine. Would’ve liked better packing.
Kristin R. (verified owner) –
Ordered on Monday, had it by Thursday. Fit my G19 Gen3 with zero issues. Quality control is on point.

Perfect fit. Zero modifications needed.

Been in the market for a while and finally decided to buy from F1firearms. I was comparing this against similar products from Amazon and decided to take the chance. Glad I did. Arrived in 4 days, well-packaged, and the quality speaks for itself. Installed it on my G23 and ran 237 rounds through it without a single hiccup. This is the real deal.

Exactly what I needed. Fast shipping too.
Brett F. (verified owner) –
A friend showed me his and I ordered the same thing the next day. No regrets. Product quality is excellent.
Eric N. (verified owner) –
Decent product for the price. Not the absolute best quality I’ve seen but it works well on my G22. Would buy again if the price stays where it is.
Josh F. (verified owner) –
Better than what I got from a local shop last time.
