Thanks for the suggestions.
I have already verified that the barrel is tight. I saw that on a couple forums. I checked out the net for a while before I posted.
My 190 says .22 S,L,LR on the barrel.
I figured that the catch was intentional, but I may just eliminate it. The problem is that i don't want to do it unless I am sure that it is the reason... or more sure than I am currently.
