hello everyone. Sorry for my frequent questions I ask, however this should be the last one for a while. I am wanting to know from any personal experience if getting a muzzle brake for my 7.62x39 AK is worth it? Will it reduce the recoil at all and help me stay on target? Or am I better just...

Just bought a Colt Series 70 Competition 9mm and I’m wanting to put a compensator on it but can’t find any that will fit a 9mm, it seems like they’re almost all for the .45ACP. I’m also wanting it to be gunmetal gray or SS. Anybody know where I can find one?? Thanks, James P.
