i just put p10's on my 179's, im only 140 pound's. i recomend p series or rossi scratch or power series because there all the same thing and they are proven to be pretty damn good. Wide brakes suck! mine cost 50 buck's extra so be ready for that but they look dope and Look p10's are the binders i plan on stickin with for the next few years. If it helps at all i mounted my pistols at 3 and a half.
