I could sure use some suggestions on this. I had about 300+rounds through my P-3AT with NO problems at all. Today I was shooting WWB value pack (95 gr. FMJ) from Wal-Mart and my 15 shot seized up the slide. I don’t remember the shot sounding any louder, the slide just froze. When I forced the slide open, here’s what I found. Here’s a picture of the casing I removed from the gun, and other casings I picked up before the incident. Obviously the split casing was the one still in the gun. The gun was just cleaned and well oiled ((Hoppe’s 9) before I shot it. My questions are, what do you think happened, and how would you handle this? ***I did a total “Fluff and Buff” before I ever shot the gun.
