Great barrels, I use them in all my glocks !! Comp works great as well, totally secure !! Just did a barrel for my P320max, cut the group size in ½ and the fit was spot on ! Such a nice product
So if you are GM in limited you would shoot the first 4 LO matches in "U" then if you lets say made "B" the next match you would enter as "M" due to the rule ?
And I wont even start on the horrid actions these new custom shop guns have, really sad to see the total crap they produce now. (and ive done smith actions for decades)
