Uberti's are nice weapons,in general good shooters.
I picked up a used Regulator recently,.45lc in a nickel finish. Noticed that it wouldn't shoot as well as my EMF Hartford so went to investigating. Found that a .454 bullet would drop right through all cylinders...not the best for accuracy.
Still,it's good enough for most SASS shooting,I'll just use the Hartford for accuracy shots.....catsup packs and the like.
