This may be hard to explain so I may need to clarify.

As the gun fires, the slide moves backwards, ejects shell.

Then it feels like the slide stops for a moment, then snaps forward picking up the next round. I am use to a very quick back and forth of the slide without a feeling of momentum of the slide moving forward.

So, is it:
1) ammunition (Federal FMJ 180g - no issue berfore)
2) ammo hanging on slide
3) something with the sear
4) something with grip like not locking wrists
5) something with the recoil spring
6) something else

Also, 100 rounds more have shot than in my signature.

Thanx for any help or advice.
