Matrix Precision Temporary Dowel (Sear Spring) Pin For Testing Sig Frames
You don’t really want to take the sear spring pin in and out of the frame, every time you remove it or install it, it enlarges the hole in the frame a bit because it is larger than the hole, as it is supposed to be. Ideally, you would want to only install the sear spring pin once and never remove it.
If you want to function test your Sig build without installing the sear spring pin, these 2mm dowel pins are a slip fit and won’t expand the hole like the spring pin will. I use them on all my builds to function test before anodizing or coating. Then I push it out with a paper clip, and thus the sear spring pin hole is virgin for the final assembly and installation of the real sear spring pin.
