Maruzen P99 problem
 

Heya'll
I've got a Maruzen P99 that's having problems. When fired, it doesnt kick the slide back all the way, and wont cycle bbs. Maybe every 1 in 10 shots fired will put out a bb, otherwise it just doesn't kick the slide back all the way.

sometimes the slide will even lock up half way (between rested and full-back). Its rare, but it happens.

I field stripped it, wiped down all the silicone oil and checked to see if there were any obvious cracks, breaks or jams. I didn't notice anything.

Can anyone give some advice? is it not getting enough gas? Im lost.

thanks for any help.
