First you need a heaver rifle !! Mine is 16 lbs and I have a brake .I can shoot it all day long with out or with the brake. I actually just re barreled and at that time I put a brake on it.
3 n 1 oil from the hardware store it comes in a nice little bottle to keep in your range bag. When I do clean a 1911 and that is not to often i assemble it back with ATF ( amsoil) . I dont clean my 1911 s but every 800 or so rounds but I lube them every-time I shoot them.
