Taurus M9 issues help plz:)

[Halestormx]

Hey guys just wanted to ask for some advice about my issues with this pistol. What's happening is that I can fire a few shots maybe 3-5 then the slide will either get stuck on the way back or on the way forward I cant tell. But when that happens all the gas from the mag is released. Sometimes the gun will do what I would call studder b4 this happens as well. Any info or advice on why or what parts might need to be replaced would be great. I will try to get a video up soon to show what all is happening if that will help.
