I have plenty of mags so my carry mags are almost never used for range time. But, that first round will be fired every 2 or 3 months. I shoot Freedom Munitions ammo which for the .40 shoots the same as my Ranger T-Series ammo, so there's no need to practice or "train" with the more expensive stuff.
