BRASF0311 and 45Man the 5 1/2" in RedHawk is my favorite barrel length. I have shot the 4 1/2" and the 7 1/2" I like the balance of the 5 1/2 best. Have you tried the 405gr RHO in the 45? Also for fun read the article on Garrett Cartridges about the 44 or 45?

A 41 in 5 1/2" would grab my attention.
