“Adjustment of the barrel´s collar for proper lock-up at the muzzle end is as simple as turning the collar. Shooters can eliminate all play at the muzzle end of the barrel without any machining…everything worked exactly the way it was supposed to. Shooting from the prone position, I watched the hole in my…target grow ever so slightly…I finally exhaled and examined the 5 shot 25 yard group that measured just .64 of an inch. Reliability was 100% with factory ammo and every bullet nose configuration possible was tired….If your looking to improve the accuracy of your 1911 without the expense of having a custom barrel fit by a gunsmith then given Bill Jarvis a call…”
