I didn't have to fit it to my 85 Combat, but would have had to do so for a couple other 75Bs I had at the time. It shot (and shoots) so well on the 85 Combat that I didn't bother to fit it to the other guns. (Doing so would NOT have harmed it's effectiveness with the 85 C.)
Mine shot as well as my beautiful stainless Ruger MKII Target Competition (long, slab-sided barrel) that seemed redundant, so traded the Ruger for a .45 Witness Sport Long Slide (the predecessor to their Match and Limited line.)
