It's pretty friggin sweet. I wouldn't commit to the purchase unless I could inspect the barrel, Looking for chatter marks, poor rifling, or an uncentered feed ramp or chamber. Mine looked good.
Seems in the couple of years since it was released they've updated the recoil spring as well to keep the slide from slamming into the frame.
Bone stock, with just a bit of lube I fired like 4-6 magazines total, mostly Winchester SuperX 40gr Power Point of which 2 rounds failed to fire with clear rim strikes that I didn't bother trying to restrike. Otherwise it fed like a champ I fired a mag of Norma Tac 22 LRN and it fed without issue as well.
I've since installed a Lakeline SS guide rod in the hope that the plastic buffer further reduces slide wear, but unfortunately haven't had a chance to go back to the range and see if it runs as reliably. IF not the stock spring ran fine.
I have a +9 magazine extension on the way.. which as long as it functions well means 25+1 capacity.
IF I'm being honest it's probably my favorite gun to shoot right now. Not that I have a large collection to choose from. Hopefully it holds up over time. Almost wish I had a tax stamp and a suppressor for it.
