I track rounds fired in a simple spreadsheet.
Tracking so I know when to perform manufacture recommended maintenance and spring replacement.
Also track issues to see if there are any increasing issues or patterns (gun or ammo).
I was particularly concerned about my .22LR conversion, but after 360 rds 2 issues (FTF, FTE). My 9mm barrel has had 1 FTF out of 350 rounds.
I know is better than I think.
