Thank you both.......dry fire practice is as good as going to the range and saves ammo.
A Buddy told Me about this one exercise from a Handgun Class He and His Fiance took.
Empty Mag and Pistol. Place an empty case on top of the Slide by the Front Sight. Dry Fire to practice smooth Trigger Contol without vibrating the Case off the Slide.
I haven’t tried it yet but I’m betting it’s not that easy to do.
