Drop in grip safety block for 2011s, No permanent modifications required just drop in on top of your mainspring housing behind the grip safety tails over top of the hammer strut and reassemble

PETG is what i used with good success, but any other strong filament such as nylon or carbon fiber blends would work too possibly TPU but i have not tested with any of those yet.

Print the part flat using 100% infill
