Hello just joined this forum. I am a proud owner of a p99 9mm titanium slide pistol. So far I have shot approx. 500 rounds through it. I had one fail to fire problem. I think it was my fault but I want to ask you guys what you all think. I switched from double to single action by pulling back the slide. I aimed and then click, it failed to fire-- waited 30 sec. and then opened the chamber to release the cartridge. On inspection the primer hadn't been touched by the striker. I then fired the rest of the clip and maybe another 20 rounds with no problems to report after. This FTF happened within the last 50 rounds out of the 500 I have shot before. Gun looks fine and I couldn't replicate the problem while dry firing at home. Any suggestions to what may have happened? Gun is cleaned very well after each use. Could it be possible to partially cock the striker?
