Anyone been shooting pistol-caliber rifles much at MCF&G? Just picked up a real nice Ruger PC9 and five stainless mag's at PSS (a fair deal from Bob, as usual) because I thought it'd be practical at <100yd range and maybe a hell of a lot of fun at FNS. It's built like a tank, serious quality here. Anybody shot one of those? This one has a nice trigger... I think someone may have worked on it a bit. Deciding what to do about sights/optics. All input welcome.
