Strange thing happened with the SR Friday. I shot a magazine, slide locked back, removed mag, inserted new mag. the slide did not close like it should have so I hit the slide release and it still wouldn't close. The mag release would work either. Racing by hand didn't help so I it up and dropped the PPQ in the snow. Picked it up and did a mag dump into the van. Came and inspected the SR. The first round was seated to high and wouldn't let the slide close. After some fiddling around I got it out. Tore it down and found a metal shaving in the mag release spring. Works good now.
Was the metal shaving lead??? Did a misfeed shave some off on something and it fell into the mag??
