Me too. Bent the one on my Rogers and Spencer when i first got into B/P. Couldnt get it to straighten even with workshop facilities. Bought a new pin from Kranks and made a tiny brass retaining pin with a thread in it which takes a stainless screw so you now have to use an allen key to remove the cylinder. Havent had any problems with the Rugers yet but its so easy to do its only luck i suppose. Bit worrying about the ROA spares situation though! Tim
