I only keep track of how many rounds I shoot on my SR9c. Because it's my only handgun and I'm curious to see how many rounds all of the stock parts will handle before I have to replace something. I keep a rough estimate in my head and just keep adding each time I go shoot. I can figure out exactly how many rounds by counting my ammo boxes. Each time I shoot a box I break the cardboard outer down flat and keep them all together in a box, so if I want to know the exact number I count the number of boxes and multiply by 50.
