Bought 2 at a gunshow for $15 ea. The followers jammed in the mag at around the 3rd or 4th shot, allmost every time. Sometimes only on the last round. Didn't matter what brand of FMJ I used. I removed the followers and cleaned up the edges slightly with no luck. I returned them to Chip. M. who were happy to replace them with 2 more that did the same thing. They look nice though, and have that cute shooting star on the follower
No problems at all with my Colt 9rd mags. I might try some Metalform 10 rounders next.
