I thought I would give an update since I hear of so many people having trouble with their 22/45's... This gun has never had any any functional problems since I started shooting it. I've been shooting the CCI or Remintgon Golden bullets to break it in.
At first, I was hesitant to buy one after all the posts I've read. I now have approx. 500 rounds through it and it has been working great. I expected a few misfeeds, but I never had one.
I attached a fake suppressor to it to get used to the weight balance in anticipation of getting my real one this fall.
One thing I just did was upgrade the trigger. I put in the full Volquartsen Mark II trigger/sear kit that also eliminates the mag disconnect. Now the magazines drop right out & the trigger is adjusted for minimal pre & over travel.
I now can shoot it more accurately than my Mark III Hunter.
