Help.....Stripped Grip Screw.....
Either get a large ez out or you can try using the correct size alan wrench, but super glue it it into the hole.
hard to tell with the glare, but it looks like a Torx headed screw.
Do not use cheap Allen wrenches form the bargain bin.
Bondhus and Allen brand are worth every penny.
The wrenches need to be correctly size and hardened.
The cheap ones are rarely either.
The metal in the bottom of the recess looks like leftover from forming the recess.
You can sometimes find a Torx that can be driven in and used for deformed hex recesses.
Looks like it was a torx to me too.
this is a good example of why to stick with regular slotted grip screws-you'll always have something around (srewdriver leatherman tool or even a knife blade in a pinch) to tighen screw- no special tools needed

NO!!!!!

Not a hex/allen head socket, and if you get the correct torx bit, there is still enough of the torx spines left to get the bolt out.
If all else fails, drill the head off with a cobalt drill bit. Then after removing the grips use a small set of vice grips to remove the screw from the bushing.
try the proper torx bit first. If that fails fully strip the gun to make sure chips or what not dose not get where u dont want them then use a dremal to lightly slot the head then turn out with a screw driver. I that fails then drill the head off slowly then grip the bolt shaft with a vise grip and remove.
I found a set of reverse cut drill bits. if you can't get out any other way with proper tools then i would sugest them. the bit will eventuall grip (don't got to fast) and "unscrew" it from the gun leaving all other threads intact. then invest in some new screws and make sure you have te proper tool to fit the hole.
you will want to use the bit that is the same size as the hole for the tool or just barley bigger.
