For what it's worth, my standard loads for the 9mm utilize either a Remington 115 grain jhp or 124 grain jhp, and with more than a thousand rounds through one of my P-1's the feed ramp shows no adverse effects. I've also put several hundred rounds of the excellent Federal 9bp ammo loaded with 115 grain jhp through my P-1's with no ill effects. Both my handloads with the Remington bullets and the Federal 9bp loads function perfectly through all of my P-1's. For that matter, my handloads with the Remington jhp's function perfectly through my lugers also.
