I'll try the wash cloth. I got into revolvers big time this year. Learned how to do the trigger jobs, put in spring kits, learned how to shoot double action accurately and wore out my finger, drat.
The 625JM was used on GB. I didn't need it, but didn't have a .45ACP revolver. Had three .45 Colt S&Ws and two Rugers. I think part of my problem is the use of the trigger finger on the mouse. May need a roller ball.
