This is the ruger miii 22/45 my stepdad has its an excellent gun but when we run bulk ammo even after cleaning it, it still jams and gets dirty quickly and we have malfunctions, then you have to get in there and clean it out. its annoying. this is why i like the revolver
Have you tried CCI's thru it? From what I've gathered, and seen, CCI's will make a semi gun run better a lot of the time.
Never bought into the thumbs forward. I switch back and forth with revolver and semi auto. Thumb over thumb. No change in my grip for either. It's the old way I was taught and has worked exceedingly well. No powder burns.
