Looking at front and rear sights, from 10-8, as an early Christmas gift for my 63 year old eyes! The video demonstrating the installation of the sights mentions tools like a vice, steel punch, etc. Since I do not have those necessary tools on hand I am wondering if I should take sights to LGS for accurate installation vs. attempting myself? Any suggestions? Also, should I be ordering rear sight with .140" width or .156"width?
