One more "conclusion" I've come to about this one.. It shoots.. It hasn't given me the least hint of the smallest issue with feeding, firing, ejecting. The only SD ammo I have on hand is Hi-Shock, but it fed it just fine..
I've run a good 300 rounds through it and I'm satisfied that it runs. Till I effect a new trigger, I don't see a need in just burning up ammo to make sure it works..
I like this gun... (It annoyed the cat and the left grip panel worked a little loose this afternoon.. Not sure I can really count that against it.)
