I bought one in 1978 or so. As I remember it came with a bushing as I didn't take the bushing off of my Series 70 when I used it. An interesting glitch I had was that it would never function on my 1913 vintage Colt 1911.
thanks but I lie the collet on the 45 ,never had a problem, there are some used collets in good shape on GB and E Bay ,will probably pick up a spare. Thankslawman,The only ".22 CU" bushing I have is in use. I do however, have several GI bushings.If you like,I'll send you the tightest one and just swap you for the collet bushing. I know a lot of folks don't like them but, I do. I've never had a problem with them in normal service.The collet bushing is suseptable to failure by removing it from its proper barrel because the big end of the barrel stresses the spring collet fingers "stretching" them. So, you're probably not helping the collet on your barrel.PM me if I can help. Regards, Nick
