STI 2011 FRAME MODIFICATION

[ss+P]

ok i had a 2011 built with an sti frame. i didn't have the trigger guard undercut and there is a nasty lip inside of the mag well (after i put a brazos big mouth magwell). How can i remove this lip and undercut the trigger guard.

Will sandpaper do the trick or should i use a file to remove the majority of the material and then sand it.

don't want to screw up the frame so i ask for you assistance members.

To undercut the trigger guard I usually use a dremel with a small sanding drum... Just go slowly.

If you go through the directions I posted in the thread below you'll see how I do undercuts...not that it's the only way, but it works. You can use the same setup to remove the lip in the magwell so that it's a nice smooth transition. I simply pop the magwell off and use a Dremel tool with the round stone I show in the link and use a little trial an error...take a little off, push the magwell back on and check, repeat until you're happy. Worst case scenario with any of this is that you trash the grip and have to get a new one...$110 or so, and it won't hurt the frame. R,
