FWIW:
A Mec-Gar came with my Custom Target. I took the bait and tried all the "name" mags, The ones I've come back to have been Mec-Gars, stainless with base pad. Now have 5. Never a glitch, hang up. I have have had feeding problems (usually the last round) with Wilsons, and McCormicks, both 7 & 8 rds.
Try them all, stay with the one that works in your gun!!
