I like both of them MFG's, but the Magnum Research's are single action as well, for hunting purpose, Id go with the SRH, due to it is double action abilities. I'm very intrigued with the magnum researches 450 Marlin model, you can also swap out the cylinder with a 45/70, a little fitting needed, neat concept, the only other thing I noticed about the researches grip, it seems to be at a weird angle and thin on the top, looks like it would be murder on recoil, maybe not just the way it looks. I have a big hand and like a little bigger grip, maybe a after market grip would fix the problem, a Hogue mono grip would fit the bill, if they make them for Magnum Research, would suit me fine.The researches I have handled seemed to be finished well, and the single action was tight as well, Nice and solid, triggers are not bad for hunting purposes either. Aim small hit small. RAMbo.
