I have a mil-spec 1911A1 and need some more mags. I only have 2 crummy Sprinfield factory mags. I am going to go with metalform brand - lots of good testimonials on the net. Is there any reason to buy welded base mags vs. removeable base mags. Also, is stainless worth the extra expense of $5.00 per mag? Since the metalforms will have a rounded metal follower, would stainless be likely to gall and cause problems? I generally prefer stainless, but the gun is mil-spec anyway and I think a shiney S/S mag would look kinda silly. Thanks for the info.
