I prefer the Limbsavers to the Decelerators I use them on my 444p, 45/70(which also has a mercury recoil reducer), my35ltdss, and my 1894 41ltdss. They were easy enough to install using a BSquare jig bought from Brownells. Just follow the instructions, go slow and you can do it. Around here they get about $100-120 to install, so if you have other rifles that need one the cost of the jig is well worth it.
