i have a p97 45 caliber , the other day at the range it faield to fire 3 times out of the 150 + rounds i put throught . it seemd to happen about midway throgh my time at the range. what would cause this? i was using value pack ammo from wal-mart the winchester kind. no dimples on the primer, the gun was cleaned two or three days before i went to the range. today as i field stripped the gun to clean it i had the slide in my hand and with a small pencil i pushed on the back of the firing pin to see how for the pin would come out of the small hole, it did not come out at all just flush to the hole. is this normal? will it come out when in battery? or dooes the hammer throw the firing pin out, somthing i cant duplicate during field stripping and cleaning?thanks in advanced for your replys
