Most likely this would not cause your issue with a grip assembling since the bolt Carrier never leaves the hammer meaning when the bolt Carrier is to the rear the hammer is compressed .Even if the Carrier moved forward at a Speeded up Rate It's still would not force the lower assembly back-and-forth. Unless your Carrier was dragging on the hammer assembly. If you removed the stock from the gun and work the Carrier while looking at the Carrier assembly you will see that the Carrier cannot move far enough back to allow the hammer to protrude upward to be caught on because the hammer is compressed at all times by the Carrier during recoil and Forward motion. Hard to say what may be causing you to have back and forward motion in your trigger group. I would check the gap between your trigger group and your rear stock plate if the stock plate is an up against the Trigger Group this would allow back-and-forth movement. Hope this helps.
Also if the weapon is recoiling too hard and striking the Hammer And Ejector at a harder impact this could be driving the pack Down and back this would a long gate the holes because of pressure Forcing it back and possibly cause a loose trigger pack since the Carrier only strikes the hammer from one direction being forward to the rear. I would check the boltgap on the weapon Is extremely low this causes greater recoil. But also you would start to see roller dents In the rear portion of the receiver also.
The biggest factory is if your Carrier in forward motion is striking your hammer you would have a major problem it will literally destroy the gun.
