very true.Best is what works consistently well in YOUR 1911.
Someone else's favorite brand or model that works perfectly in their weapon, may not prove so great in mine.
Old GI Joe mags are quite valuable now that CMP buyers are looking for better quality magazines to match their recent new-old pistol purchases.My full taper GI feed lip mags only really feed ball ammo reliability- for me. I have Wilson 47 (7 round) and 47D (8 round) that feed hollow point ammo reliably. The 47D is almost impossible to seat on a closed slide though. Keep in mind, the tube is the same, the followers and springs are different. So they find room for the 8th round in the 47D by removing the legs from the bottom of the follower and putting in a spring that stacks shorter. I also have several Checkmate 7 round, hybrid feed lip, GI flat follower magazines that feed everything. I just traded some old genuine GI magazines with Ed Brown for his 8 round mags ($10 each) they have hybrid feed lips and Checkmate followers. So far, they feed everything and have just a little more room than the Wilson 47D to seat loaded under a closed slide. My sample size is only 2 pistols - one Colt and one Les Baer, so YMMV.
Wilson mags other than .45 are the only ones I’ve ever had problems with.In .45, Wilson & Chip McCormick (shooting star) have been 100%.
But in 9mm, the Wilson's have been nothing but trouble. I bought 2 of the 10rd mags for my Springfield RO. (10rds vs 9rds) for IDPA. The Wilson's will regularly feed screw up within the first 3 rds. They are worthless for why I wanted them. The Springer factory 9rd mags are perfect.
