FWIW - I fired 50 rounds last Friday through three different S&W 442's. It was a mix of 130 Federal FMC, 130 grain Winchester PDX-1 and Speer 135 Gold Dot JHP.
I was attempting to find out if there was a POA /POI shift at 25 yards. (There was a 2 1/2 - 3 1/2" shift to the left with all three weapons.
)
Bottom line is that today (the following Tuesday) the web of my shooting hand is still
very sore.
I was quite surprised as the only other weapon that ever did that to me was a Ruger Redhawk 5 1/5" .44 Magnum firing Remington 240 grain JHP loads with stock wood grips.
Now, you are probably getting a reading on your "Wimpometer," but in my defense I can truly say that because of my employment, I have fired is excess of a million rounds of center fire handgun ammo, and up to now only the Redhawk had nailed me.
I was hoping that the Hogue "Tamer" grips would make a difference when firing a 16 oz. small frame handgun, but perhaps not.
