OK, have a 65-3 3" old police gun. Outside is really clean..95% or better. When I put the pistol in full lock-up I have a very little bit of front to back play, very little, less than 1/64 inch (don't have a feeler gauge) and more side to side, maybe 1/32 inch. How far off is this from new? I'm sure this seems like a really useless question but I'm curious.
