I have an LRPV with the red target trigger, that lets off about 8 ozs. I was wondering if the difference betwwen the red trigger and the others is only springs and if so where can you get the springs at. I have a model 16 gun & 3 model 12s besides the LRPV and would like to lighten them up some. I know a lot of guys don't like the accutrigger but I do & would like to get all of them working like the target trigger. Thanks in advance for any help, Jim
