Fairly new Glock owner here, I just bought a new G17 today to use in IDPA matches. I have a G26 already, (and a whole bunch of 1911's), but wanted to try a G17. I've been shooting IDPA (with a 1911)for quite a while now, and doing quite well with it, but began noticing how well the G17 does in these matches, with their low recoil, quick target aquisition, and very good accuracy. I plan on installing a 3.5lb trigger, but was wondering what else should be done to the G17 to make it competitive. I'd like to use it in my next match which is 2 weeks away. Any pointers or suggestions are appreciated.
