I think its very important to know how many shots you fired and how many rounds remain in your firearm whether youre practicing or in a live fire situation. When I practice I count my shots. I know I have 5-shots with my LCR and my SP-101, 6-shots with my speed 6, 10 or 17-shots with my SR9C (depending on which magazine is in), 15-shots with my Glock 19 and 20-shots with my Mini-14. I think its a good habit to know how many rounds remain before I reload or run for cover. Do any of you practice the same way?
