Now that I've tried "other" (see WOW thread) guns I'm done with my G-17. I never particularly liked it anyway, but I'm done. I only had it to compete in GSSF matches anyway. I may continue to do that, but only as a side thing when convenient. Probably won't go back to TMP for the Nationals again. I've score 498/500 indoor league and <71 in outdoor match so that's pretty close to my goals (one shot away in each case).
After much debate I decided to go with the Sig X5 Legion. I already have a P320 (3.9" barrel) that I have grips and magazines for. It qualifies for CCP in IDPA. I could use it for SSP in IDPA or Production in USPSA, but I'm at that level where I could benefit from a really good gun. So I've put my name on the waiting list at the LGS.
Over the last 15 years, in competition, I've shot P99, XDs, M&P, G17 & 34 and the P320. If you're looking for the "one" gun to carry and compete they all do good, but now I want a "competition" gun.
