Hey, I need some advice/suggestions. One of my best customers brought me in a pistol yesterday, a Ruger MKIII .22/45 Target model pistol w/ 4" bull bbl. It is in great shape, customer bought itused and supposed to work fine. Problem is that it won't cycle. Bolt barely blows back on firing, and slams the empty case back in the chamber. I disassembled and cleaned the entire pistol, down to the last spring, and reassembled. The chamber appears smooth, and the extractor is sharp and has plenty of tension. The ejector has a loaded chamber indicator attached to it, and Im suspecting a problem with it... anyways, it still won't fully cycle, and I've tried 3 brands of standard velocity .22 LR ammo. I specialize in bolt rifles, AR's, and 1911's, but will undertake anything. My experience with Ruger .22 pistols is unfortunately limited to installing a new sear stop pin and spring in an old Ruger .22 standard (before they designated "Mark I, II, III). Got any ideas? Perhaps the recoil spring is too strong? As I said, she just bought it used, so we dont know if it ever worked properly... the pistol appears to be nearly new, shot very little, Id guess less than 250 rds. Thanx!!
