Ran the gun with some tape over the emitter and used the irons in IDPA this weekend. The gun did very well, sadly I did not, two stages did me in and I placed 9/21.
One thing I'm noticing is that with the slide refinished I seem to be getting a little more drag on the rails and have having some intermittent failures. The fit of the frame and slide definitely feels tighter so I plan on just shooting the the gun a lot and letting it "break in".
It's been to damn hot of late to take the gun to properly zero it with my carry load, but I have a workable zero for now. Hopefully if it cools off this week I can take it to the in-door range and rest it and get my dope where I want it.
A 50' zero with 124gr+P HSTs should be pretty good. Will also run some NATO through it see if that loosens the fit back up.
