I will need to shoot at least 200 more rounds of 124gr Lawman or PMC FMJ before trying the GoldDot I have.
The strange thing about this R9 is that the 115gr hurts the most. It doesn't kick much, but the recoil is more of a sharp slap, my hand starts to shake after 3 magazines. The 147gr kicks a bit more but doesn't make my hand shake, so it is more controllable. The main problem with 147gr is that it seems to cause the slide to unlock early, there is a long drag mark in the primer, that can't be good for the firing pin tip. 124gr recoils softly and is fun to shoot.
The best accuracy so far came from 124gr Lawman. Out of 12rd of slow fire, 11 were within 2x2" @25ft. Group center was within 2" of point-of-aim.
Amazing little gun.
