i just picked up an used 45 colt/45 acp recently,and today was my first day at the range
with it. the colt cylinder did just fine considering this is my first time shooting this ruger,
the only problem was the base pin kept on moving forward after a couple of shots.
at one point it was out far enough to prevent it from cocking.
i will probably just get a belt mountain pin,but do you guys feel it might be worthwhile to contact ruger. dan
