one more time 'what don' kill ya, makes ya better'.
oh, my bad, welcome to the forums. and did you do the 500 in one visit?
for me it was the 40SW in the Sigma. hits like a 1911, heavy. the grip angle is spot on. the grip itself and the loaded weight make it easier to handle. the first 10 are tight, the last 5 start to wander as the recoil begins to take a toll on the shoulders.
