Take a read on this as to things you can do. I haven’t installed my Tritium sights that I got for X-mass yet and haven’t polished up the inside bits as I have been spending most of my time building my Hot Rod motor. The FIRST thing out of the gate that I had to fix was the HORRRIBBBLLLLE trigger reset. Feel free to give me a shout and I can walk you through it easy. No grinding or cutting just turning as set screw.
