Had a squib round in my PX4 9MM today.
Remington, 115 grain JHP 9MM. (Green box, 50 rounds)
Bullet left the barrel at reduced velocity. Normal sound was muffled. Failed to eject the casing, empty case ended up back in the chamber with the slide closed and locked. Hammer was _not_ back so would have dropped on empty case in double action. Casing had extra scorch marks along half it's surface from rim to muzzle end. (Not normal.) Not deformed in any way.
The slide probably didn't come back far enough due to reduced powder load.
The important part, hot gas and fragments came out the back of the slide between the frame and the slide past the hammer directly at my face.
I have two small fragment cuts and slight burn on the cheek below my left eye. Had hearing and ballistic glasses on so no eye damage.
Field stripped and revealed no apparent damage. Fired another 120 rounds through it just fine.
Remember to wear eye protection for any practice shooting.
The PX4 with poor ammo has certain failure modes that can eject hot gas and powder fragments right directly at you.

Which model PX4? I have a full frame 'F' and a sub compact 'f' both in 9mm. I have a ton of rounds through the full size and never had a single issue.
Full frame model F. Decocker, big safety lever, 17 rounds, all that.
I love my px4, never an issue in 2000 rounds. Good to hear all is well. Bad rounds are going to turn up.

Case didnt eject either.
Sounds like a FTE due to an under powered load.
Not sure on the terminology. Low powder load and FTE is probably more accurate. I just like the word "squib".
Sure was a surprise to get zinged when behind the weapon though!
