That's a shame, I have an original marauder that I would put conservative estimate at about 20k rounds through it without any hiccups. I used it as a competition gun, bought from my buddy who also used it for a competition gun. It's still got the factory recoil spring in it.I was ready to buy one. I’m the type of guy that maybe would put 500 rounds thru it a year, but I wanted one, because my buddy had one. They feel great. My friend maybe ended up with a lemon ,it went back to Texas a couple of times for repairs. That kind of turned me off to it.
My P and P-DPO threaded have also been flawless.
