I mean, will the repetitive training with the DAO become like muscle memory?
Yes. The more you practice and dry fire, the less youll notice the trigger.
Just concentrate on your sight alignment as you stroke through the trigger and it will get easier as you go, and your rounds will go where you/the gun were looking.
Also try to "call" your shots as they break, this will emphasize your focus on sight alignment and knowing where the round was going when the gun went off.
Dont let the weight bother you. Heavy and clean isnt near a distraction as much as gritty and crunchy, no matter the weight.
