Last night I put a wilson bullet proof slide lock in my loaded. No reason except I had it. Today at the range I was shooting about 8" low at 25 yards.
It could have been just a bad day but my loaded is my most carried, most shot, best shooting hand gun I own. I have shot my best 25 yard groups with it and it's my go to handgun that I've never really shot bad with.
Im going to put the original slide lock back in and retest later.
