Thanks guys. I think I'll go with the low end at this point. Seems to group well, I'm getting the power factor I need (shooting USPSA and Steel Challenge), and recoil is low. No jams or stove pipes so it also seems "hot enough" to safely cycle the pistol. For what it's worth, I'll post some photos of the groups. If for nothing else someone else may dig up this thread and it could be of some help.

Coach.
