Heat isn’t the main thing that wears out your recoil spring, but it can definitely add to the wear over time, especially if you’re firing a lot of rounds in a short period. The big factors really are the number of rounds you shoot, the stress from cycling, and how well you keep the spring clean and lubricated.Do recoil springs wear out faster in hot weather? I’ve got a Glock 19 that’s seen about 5000rds, and I’m starting to wonder whether the heat speeds up the wear on the springs. When do you usually swap yours out?
