I've got a springfield mil spec from 1990 that never fails. It's box stock. I've got a Norinco milspec that's box stock. It never fails.
I ruptured the barrel in the Springfield doing double taps and I had a squib on the first shot. It took a bit of extra force but I got the slide open and the pistol disassembled. I ordered a replacement barrel from Midway and it dropped right in. No hand fitting required and it shoots and runs as perfectly as it ever did.
What's not to love.
