Okay, I finally found a decent deal on a long sought after S&W 310 Nightguard. Now on to the next 10mm! I already have both a G20 and a G29, but would like something a bit spicier. So I'm thinking I may need a longslide. Who here has one and can answer the following questions: 1) First of all, was it worth it? (I know this is subjective, but I had to ask.) 2) Ported or standard? 3) What kind of performance improvements are you getting (velocity, recoil, accuracy, follow-up shot speed, etc.)? 4) About how much $ did you dump into your longslide? 5) Any, "I wish I would have..." thoughts? If I go ahead with the longslide, I was thinking about having it milled for one of the micro dots, like a Dr Optics. Any input? Anyone who has pics of their G20 longslide I'd love to see them. Thanks in advance!
