I think the newer fast twist favors the 115's, at least in mine and a couple other posts ive seen. It's a great gun when the trigger is done. Got mine about 4 months ago, but I have to say, a new Sig P320 for $550 w/ 2 mags and 2 extra mags as a limited time offer, or the new H&K VP9 for $650 would be VERY tempting. They are getting great reviews, especially the VP9 and they will probably be in my possession by the end of this year (both).
