FWIW...

I have 3, 19/20 round mags and only one still holds open, seems like after a lot of use the springs do weaken, the mag that still behaves definitely seems to have a happier spring (For the time being) But like Scott says they cant guarantee they will always hold open! That said I very rarely run the gun dry so it really isn't an issue!

I`m just happy I can stuff in more ammo!! I only got 11 in my Buckmark and 15 in my IJ 1911!!


Looking at the 10 rounder's (I`ve got 2), I don't think they can be converted
