Congrats on your purchases. The Ruger P95 is one of the most solid and well-priced 9mm Full size pistol out there. Its actually kind of hefty and bulky, so that should already reduce felt recoil compared to other lighter pistols.
You can try using workout gloves if it helps. I use them sometimes when shooting for longer periods of time. It also helps you grip better and eliminate sweaty palms/hands.
