I have read through the manual several times and see nothing about dry firing. Does anyone know if you can dry fire a Ruger Security 9?
You can dry fire as many time as you want. You can also use snap caps, I use the plastic insert that come with it. It is the plastic empty cylinder indicator.
I don't do much dry fire of mine. I find the trigger is pretty good on this pistol, and don't really feel I need that much dry fire practice with it. As stated above, snap caps are a cheap investment.
