Thank you I do sometimes play around with refinishing, but when it comes to fileing, or fitting, I have learned to send it off. I messed with iot a little last night unloaded, and couldn't get it to lock up...so I went to the range after church this morning....and loaded it did it once each on each of 5 full cylinders... So my plan is to with a pick, clean the stop indentations on the cylinder, and then clean carefully the stop and its cavity, and see if I can get it working reliably...I just messed with it some more empty, and I can't get it to fail...seems strange that the weight of the rounds in the cylinder would make a difference...my other though was to clean under the star and see if there was some issue there...loaded vs unloaded...my next experiment...empty cases in the cylinder...to see if I can get it to fail....very strange
