I have three systems:
1- Competition pistols. I keep a shot log with each gun which includes scores, sight settings, ammo mfg, type, lot #, or components & data if handloaded. I don’t really care what the round count is, just how they perform in my guns.
2- High end toys. I don’t collect, but these would be considered collectors guns by some. I keep a small book with each gun and shoot in easy to track numbers; 25, 50, or 100rds. These I only track in case I decide to sell.
3- Plinkers & Service pistols. Don’t care. Clean them & replace parts when they start failing. If I sell a Glock the practical difference between 5000rds and 7000rds is nothing.
