Ok let me try and explain it, have a older 870 mid 90s it has a metal trigger guard if that matters. And when I try and shoot very fast it will sometimes prevent me from sliding it back untill I take pressure of forgip, then it will. So I pull the the trigger and try to rack the gun, and if I dont give it a pause and if I pull back to early it wont pull back, so ill have to relieve that pressure then it will. Doesnt happen on a new 870 with plastic trigger group. Any thoughts.
870 slide wont slide back if pressure is on slide to pull back....

It could be the barrel not the trigger groups.
Sounds like cheap target loads and a rough chamber.
What loads are you shooting? If its low brass, aluminum shells this is a common issue, and a chamber polishing is an easy fix.
Cleaning rod, and a 12 guage mop wrapped in steel wool in a drill with a little oil works well.

Just with snap caps, it not getting stuck it just wont slide back if I try and cycle the gun to fast after pulling the trigger, it would be like pulling back on the slide before u pull the trigger then when u do, the gun still wont rack so you have to stop pulling back for a sec then it lets u cycle the action. But miners doing it after trigger is pulled and finger released.
Some 870s won't unlock easily unless there is some forward pressure on the pump before it's pulled backwards to cycle.
The 870 is designed so that the recoil impulse will supply that bit of forward pressure, as a safety measure to ensure that they won't unlock prematurely, however in some guns the recoil impulse alone won't do it.
My 870, as well as a friend's with a consecutive serial number, required quite a bit of forward pressure to unlock, until we did a bit of careful stoning on one of the action bar engagement surfaces and now they run as they should.

The lockup you're referring to requires constant rearward pressure, which is impossible to maintain under recoil.
How you hold the 870 under recoil has a huge effect on how it cycles. It is possible to hold it so that you get a "bounce" that will do the work of the rearward cycling for you. This can make for very, very fast cycling.
"...mid 90s..." That isn't old. Mine is a late 70's vintage and doesn't have any issues like that. Your issue has nothing to do with the ammo or the trigger guard. Nor do you need to polish the chamber. Forget the snap caps too. You don't need 'em.
I'm thinking with Dsiwy. A newer 870 designed by law suit frightened morons.

Snap Caps?
So you haven't even fired the gun yet?
Go shoot it and then lets see if there is really an issue.....
