Good magwell for the money - Glock 50431 Modular Magwell G17, 34 Gen5, G45 Black Polymer

I put this mag well on my Glock 45 and it fits well. The only complaint I have is that it isn’t secured to the front so it has the potential to move when pressed. If you’re “balling on a budget” this a very good mag well. If you carry appendix then it might print a little bit on account that it adds about a half inch to the frame. Shouldn’t be too bad though. Overall would recommend
