I put a Hogue Monogrip on mine and it works well; personally, I've never had a problem w/torn or abraded skin, but YMMV. The stock SBH grips were another matter. Maybe when I was 9 or 10 years old the grips on Rugers or other single actions would have fit my hand, but the stock grips let the SBH bang the crap out of my hand, esp. behind the trigger guard. I also prefer rubber b/c when I'm shooting heavy stuff, I want the gun staying put in my hand. And I like full-length grips b/c/ I want all my fingers on the gip, not wrapped under or dangling when the gun goes goes off.
Apart from velocity diffs between mags vs. specials or reduced vs. full power loads, bullet wt will also have a huge effect on POI. Mine shoots Fed 300 gr Castcores abt 2.5 in higher at 25 yds than it does full power 240 gr.
