Will a 5.5 bull barrel make that much differnce over a 4 inch for one hole groups.

Step up to a .50 loaded with wadcutters, and it gets a lot easier.

Besides, for a 22LR, a group needs to be less than a quarter inch to be "one-hole."

you just keep shooting until there's only one hole, eventually you'll either run out of paper connections or ammo.

ordered a Primary arms Micro red dot , Looking forward to trying it out on the Mark I. Can't believe $20 for a mount, and $60 to drill the holes. Found the instructions how to drill and tap for a mark I, may just set up my drill press and do myself. Got scrap gun partsl will try on that first.

Thanks for the comments. If i ever need to buy another hand gun it will be stainless plus drilled and tapped
