Yeah, that sounds pretty cool. For SD, 10mm or 45 Super will be my limits and I'm not scared of some recoil. NOTHING beats a revolver in SA for hunting though. Since you're set for Rowland in semi auto SD platforms, I'd consider a 625 with reamed chambers and a trigger job for hunting or a "reach out and touch someone (with a cannonball)" HD/truck gun. No worries about it handling the abuse.
