Mr Graham , a quick question.
I switch barrels on my glock, stock 40 and Wolff 9 mm
Will this have any effect on the part ?
Quick review, I have always loved my glock for its fuction, it ability to group has alway left me wanting a little more.
I must have had the sloppiest slide lock glock as have produced.
Your slide lock has cut my groups in half.
Thought maybe it was a mind thing, switched out on the range.
Allowed some one else to shoot, as well as my self , right back to sloppy groups.
I am very pleased with this drop in part.
