I've had a Ruger MK II bull barrel target pistol for 20 years. It still runs fine, and is very accurate. I bought the Victory specifically because of the comparative ease of taking it down for cleaning. That and a bit better ergonomics. The instructions for cleaning the Victory specify taking the receiver group off the frame, removing the bolt, and cleaning from the breech. I could do it differently, but I don't want to. And, yes, I do clean it every time I shoot it, same as every other firearm I've ever owned. I should be able to follow the manufacturer's instructions and expect the gun to work without falling apart. The fact that there are fixes to work around the problem does not alter that simple fact.
