Good morning everybody, I am currently getting ready to ship out my new Kahr P9 slide to XS Sights to have them install some Big Dots. My other 2 carry guns are a Glock 19 (Meprolight 3 Dot), and Sig Sauer P232 (standard factory iron). Obviously the sight picture on all 3 is quite different, but I was wondering if it might be a good idea to try and keep the actual sights on my 3 different guns the same so that I am at least working off of the same "foundation". I practice with all 3 regularly, and the Kahr and Glock get the most carry time. What do you guys think?
