Thinking of purchasing a m&p 45 and getting the 460 rowland. Skeptical to say the best. Does anyone know if there is anyone know of a way so that it isn't as hard on the frame on the m&p. I was thinking of maybe a 24-26 lb recoil spring if someone makes them(haven't checked). Looking for something that can multitask and don't wanna buy a gun in 10mm or 44mag and just have it solely fill one roll. The primary focus of this will be woods carry. All I got is a 9mm with the +P+ 147 grain fmj's from underwood in it right now and if I come across a black bear or a moose I want something bigger then 9mm no matter how much of a +P+ it is.
