Quoted: I bought some "chip McCormic" mags on e-bay. They work well , but don't drop free from my SA. I don't want to have to pull out empties, Prefere they just fall out when released. |
Shooter62, I had a similar problem once, although I forget with which brand of magazine. Turns out my problem was not the mags, but that one of the grips screws was a jillionth of an inch too long, and was sticking into the mag well and contacting the mag. Check your mags -- if they have a faint scratch line down the side, you may just need to file off a little bit of grip screw. If not, then yes, the mags are too fat for the mag well.
I have had good luck with most mags. Wilson, Shooting Star (McCormick), Mag-Pack. The only ones that don't work reliably for me are the two Mec-Gars I bought recently. I only bought them because everybody says they are the most reliable, but not for me. Apparently, I am the only person in the world whose Mec-Gars don't work. Can't get them to feed even hardball in any of my 1911's.
I have had several Colt magazines break, always in the same place. There is a square cut at the rear. The crack always starts in the left corner of the square, and the left feed lip starts to spread wide. On other mags, the cutout is circular or at least rounded.
I had a Wilson plastic floorplate break once. One of the little rails where it slides into the mag body started to split off, and I was getting lots of failures to feed. That was over 20 years ago, though. I still carry Wilsons a lot, and haven't had problems since.
