I am laughing as I type this regarding the comment, "it is overkill or insanely overkill for a hog." You are right, but I think I just gotta have it. Ruger lists the guide gun and a Hawkeye chambered for this caliber in left hand, but the recoil pad on the Hawkeye looks to be almost non-existent, so I'm going for the Guide Gun if I can find one. Plus I think that the muzzle brake can only an added benefit.
I have a Marlin Guide Gun, .45-70, and I don't find the recoil with hotted up Buffalo Bore ammo particularly objectionable. How does the 375 compare to that?
