I have a MechTech CCU (One of the earliest versions... still a lot of fun!) for a 1911 frame. I have used 10round mags in this forever but mostly because the higher-capacity mags I have seen seemed dodgy or had bad reps. It has been several years since I looked around and I thought I would see if things have changed at all. Are there any higher capacity 1911 single stack mags out there? What brands do you reccommend?
