I would like to start by thanking everyone in advance for your help and advice. I’m in the market for a 9mm. A shop I frequent has three used pistols that have caught my eye: S&W 3906 $350, S&W 6906 $429, and a HK USP Compact, $529.( I hope the model numbers are correct.) All are in great conduction, especially the HK (looks NIB). I’m not much of a pistol man, so I need some advice. Are any of these a good deal? By the way, it would used for a range gun and maybe some CCW and IDPA.
