Magazine for Sig Sauer P220 .45 ACP 10 Rounds Blue - 45 ACP Caliber, Aftermarket Origin

Malfunctioned more than it functions. Rounds nosedive and jam on shot 1-3 then fails to chamber round 10. Terrible quality range mag for failure drills only. Very disappointed.

The magazine Jams the slide everytime.

Do not buy these. Springs jammed multiple times when loading on both 10 round mags for my Sig P220 .45ACP (one nickel, one blued) that I purchased. More concerning and now relegated to my range bag only (defeats the purpose of the extra capacity for personal protection) is the fact that both have consistently jammed on one or more rounds, always the last round jams b/t magazine and chamber (always as in every one (100%) of the 10-12 times I've used them the past couple weeks at the range) and often an additional round mid-magazine will also jam about 60% of the time. Total junk. I would not sell these in my store and am exploring a return but I don't think you can return mags. Note, the pistol is brand new, Sig 220 Equinox .45, nothing wrong with the pistol and all my other Sig mags and Act-Mags work perfectly fine through the first 500 rounds, not one single F2F etc. from those, but 100% F2F issues with Pro Mag.
