Thx for sharing the information.
Yeah, the manual is a great source of maintenance info.
It’s a known fact that short barrel handguns need frequent recoil spring replacement.
Every 2500 rounds sounds not so bad… CZ RAMI2075 needs it every 1500 rounds.
Fortunately this is not expensive part. If someone doesn’t like to change it frequently and is willing to spend more money, flat springs can handle more rounds.
