Will the Endo stock fit on a 21SF frame.

I have a G21 Gen 4 SF PDW. It took a fair bit of Dremel work.

Mine has the rear hump on the grip removed but the finger grooves are still there.Can you tell me where you had to Dremel to make the Endo work.I could also email you a picture of my 21SF to see if it would be worthwhile trying.

The Endo won't fit your gun then if you've had the backstrap filled and re-shaped. The Endo fits into the hole in the backstrap.

You could pick up a standard (non SF) 21 frame pretty cheap though and use that; the Endo fits those with no modifications.
