Has anyone had any luck changing the mag release? I tried to install a Wilson extended mag release and it does not fit. The mag release itself does not sit flush with the frame and the mag catch lock from the factory mag release does not fit in the Wilson mag release.

I haven't. Then again, that one area i never have any trouble with due to my long fingers. There are simple extended buttons you can drill and tap your existing button for. I put something like that, only with an extended wing on my buckmark for the lady since her fingers couldn't reach even with turning then gun 45* in her hand.

Never had any problems reaching and doing pretty quick mag changes on my GSG and never thought about changing it out but let me know if you have any luck finding a solution, I'd at least want to check it out.

This is what i added to my buckmark (control layout same as a 1911).
