About 10-11 years ago a local guns store had a used HK P7 for $600. Looking at what they are worth now, I should have bought it. It was a PD trade in, so it had holster wear, etc but still. Thankfully, I did have the opportunity to shoot one shortly thereafter so at least I can say I shot one. Really cool gun. I've shot a .40 HK USP, the Sig P226, 229, and 220k. as well as a Beretta 96FS. Also numerous 1911's-Colt, Kimber, S&W, and Rock Island.
As far as the 1911, I like the Springfield Ronin Operator they had at my LGS in .45. I may have to get it. I'm holding on to my PX4 in .40, though I have someone interested in buying it, it may be a few months. To be honest, I'm afraid to list it on gunbroker because there is no paypal/venmo, etc, I'd need a money order or certified check. I feel weird about that.
