Re: Best 1911 mags?
Trial and error to find whichever brand runs best with your 1911.
I've had issues with a few Wilson 47Ds and a CM 10rd Pwr Mags - granted a few years ago so there may be some minor design tweaks??? The odd thing is my ex W CQB 5" hated WC 47's - go figure.
I have been using Tripps with the hybrid follower, no issues. I also run Wilson 47D's that have proven to work well, as well as the factory mag(s).
Try Tripps, the new WC Tact Elite, DL Sports new 1911 mags (DLSPORTS.COM), Metalform, 47D's, ACT, Novak.
I would guess there are a few 1911 shooters in your area that would be more than willing to let you run a few rounds through their mags. Just an idea.
May want to check out 1911forums. Although you'll get the same names and those listed here and the above posts. Also, may want to post what you have coming - since experienced shooters with your new setup could save you a step or two and some $$.
