My 4" 22/45 III is surprisingly accurate but it took several hundred rounds to 'settle in'. I only remove the can for cleaning since the stubby barrel doesn't seem to 'hang' well w/o the muzzle weight. Son's 22/45 LITE is even worse. With the mounted Form 1 muffler, mine is virtually same as a 10.5" bull barrel version and carries fine in a handmade holster that accommodates both muffler and Burris FastFire 3.
