edwierd , do what i did to 1 of my 34's it had a habit of loosening up the front screws . i took 1 to a hardware store [lowes ] and got 2 screws that were 1/4" longer and 2 nuts . i had to grind the nuts and screws down just a little , i screwed the new screws in tight and put the nuts inside on the screws and tightened them up . it hasnt loosened up any at all and that was over 1000 shots ago . cost me about $1.25 to make a permanent cure
