Or a 40 hour third shift work week plus a woman at home with an active outdoor lifestyle and a squad of Marines to manage (unpaid) in between drills.
I, personally, have too much crap to do on a daily basis to dry fire 100 times every day. I do about 25 from the holster daily. Now the OP, he could be retired for all I know. But I work, handle the admin and training needs of 8 Marines plus myself, and I have a fiancée to keep happy. I wish I had more time to practice but I don't, not without forsaking too many other things that have to get done.
I never said forsake dry fire practice entirely. I merely suggested using some beginner gunsmithing techniques to improve the trigger pull in lieu of pulling the trigger thousands of times. Plus dry firing that many times wears out main springs, firing pin springs, etc.
