Hammer fired will be your only option for strings without recocking. I bought the g sight laser off of amazon for 30 bucks. Paired with their app which you can pay 5 bucks for every mode on there.
Pair something like mantis x with a laser and were talking some serious dry fire training.
Glad you ain’t out there wasting ammo by target shooting. When the injuns are circling the wagons it ain’t no time to practice since every round is a precious pearl. Pretty sure John Wayne cautioned Gabby Hays about doing nutty stuff like that back in some old cowboy movies. Good job!
