Me and my brother both recently acquired 22/45s. I bought an Uncle Mike's Sidekick #5 for mine (4.5" Slab Sided Barrel) and it fits real nice. My brother has the 5.5" Bull Barrel w/adjustable sights. I want to buy a holster for him. Looks to me that Uncle Mike's #6 is the ticket. Can anyone confirm that?

I just received my Ultimate Cliploader and it's awesome! I'll buy him one of those also.
