i doubt 31 lb/ft and 55 FPS would make a big difference operation wise in a HP.
It was not a big difference--I had 6 failure to feed out of 100 rounds with Remington ammo and no problems at all with 100 rounds of Winchester ammo.
I did a slight adjustment on the magazine lips which seems to have solved the problem with Remington ammo.
I just want it to be known that all of the Remington 9MM ammo has less muzzle velocity and and less energy than the comparable Winchester 9MM ammo according to the factory links that I posted.
Something to think about when choosing ammo.
