Hundreds of people on this forum have or have had Ruger P95s (I have one) and this is the first problem that I've ever seen with one. That is VERY unusual as these guns are typically 100% reliable, built like a tank. I would take them up on their offer of a new replacement weapon and try it out. The liklihood of getting 2 lemons from them is extremely low (as the liklihood of getting 1 is so low you have to dig an 8 foot hole just to see it). If there is a problem with the second one, then it must be ammo related. What brand and type of ammo are you shooting? I've never heard of a P95 being ammo sensitive, but there's always a first time.
