So I ended up with two new sig p320, one is a compact version and the other a m18 version. I have shot the compact version and like it. I have not shot the m18 yet. I am guessing I would be able to sell the m18 for more since its still new. However I have a Wilson combat grip module for the m18 plus the m18 has the slide I can mount a red dot on. Which one would you guys keep? Not planning on carrying the p320, have a p365 for that.
