Hi. Is there a rule of thumb on how many times a SD cartridge can be racked, ejected, and then reused? I have one handgun that I use for concealed carry, home defense, and training. This means I’m regularly racking a cartridge when the gun is in self defense mode and ejecting it a few days or a week later for dry firing and/or range time. FWIW I use Federal 124g HST in a Glock 45. Thanks.
