So, the Ruger was pretty new, only 20 rounds through it (I thought). I had it put away in its case after trying it out at the range. I checked and reinserted the empty mag and pulled the slide back to check the chamber. It didn't lock back on the empty mag. Seems I had fired 19, not 20. It stovepiped, and I pulled again, my hand slipped, the round rechambered, and bang... I immediately put it up for sale, and after selling it, bought an American with the safety.
I had a couple of spare mags extra, and later discovered of the 4 I had, three had too-short springs and wouldn't lock the slide back. Ruger repaired them with new springs for free. It meant that the new one had a weak mag, as well as two I had bought new at the store previously. I called the person who bought the first American and warned him of the problem. He said his two mags worked fine.
