SS80 80% Glock 43 Kit, slide lock lever brace

This is a part for a SPECIFIC pistol kit ONLY:  The SS80 80% Glock 43 Kit with the thin, interior triangular relief cut that allows the slide lock lever to shift laterally side to side, causing it to slide off of an empty magazine nub.

THIS PART WILL NOT FIT OR FUNCTION IN A PRODUCTION GLOCK 43 OF ANY KIND.

I have this part in my SS80 and the pistol now functions perfectly.  I printed it out of Inland Tough PLA, 100% infill, on my Mini Prusa+
