I'm a firm believer in minimizing unnecessary administrative handling of loaded firearms.
I'm uncomfortable unloading and loading my Glock daily for dry fire practice.
My M&P is normally unloaded and stored in my safe.
Is it going to make any appreciable difference if I use the gun I don't have to load and unload everytime I practice with it.
As a side question I also have a Third Generation S&W where I'd be practicing with a DA trigger that also is normally unloaded. Would that be a better choice?
ETA: I also have a training gun from a lazer trainer it has Glock sights and the trigger simulates a Glock trigger but the grip is smaller.
What about that?
