I decided to put my 5.5 inch target barrel from Volquartsen's bargain bin on my 22/45 frame today and got in some practice.
The pistol felt great. A bit heavier than it is with the stock Lite barrel but not uncomfortable. The target barrel is not tapped for a compensator but with the extra weight I didn't miss it. Muzzle rise was limited and I never lost the front sight out of the target.
I shot CCI Blazer 36 grain and Agulia Super Extra 40 grain bullets today. All fired first time and shot very well out to 25 yards. I think I'll be shooting this configuration at our next Steel Challenge match or if I really want to go rogue I'll put the 10 inch barrel on. I'm going to practice with it next week.
