I recently bought 3 15 round USA mags. They al fit well and dropped well before they were fired. After shooting 15 rounds out of each of the mag, 1 mag loaded, but then would not unload. It owas a bitch to remover, and now it is almost impossible to insert fully. There is no visible damage and the others work fine. Any suggestions or ideas?
USA mags are not known for quality.
Thin metal, poor heat treatment and usually out of spec.
You probably got 'em for well under $20 a piece, the price of this lesson was rather cheap...sorry.
Original Taurus 10 and 15 round mags are still around, as are Mec-Gar...those will work.
I think you can send it back for replacement, if you want to bother.
