At what round count should the recoil spring be changed?
Thanks, JD |
| If your useing standard preasure 9mm ,you may never have to change it .Most off the shelf 9mm is under nato spec and not hot enough to make your recoil spring take a beating .If your fireing a lot of +p ammo than I would change it every 3000 rounds. I have a Glock 17 I bought new in 1986 and it has over 6000 rounds of mixed ammo and the recoil spring is not any worse for the wear .it is almost as good as new . It will be replaced along with the rod this week ,because I just got a new rod and spring . I have a S&W M&P 45 compact that I installed the Apez comp kit in ,and it has made the M&P a dream to shoot . Anyone with an M&P shoud give Apex a try . |

I'm guessing that SGB and I am looking at this the same way... any spring will loose effectiveness after some number of "cycles". Cycles don't have to be complete to eventually wear a spring out, every load/unload cycle the spring receives will shorten it's life a touch. What the exact round-count is for replacement? Dunno. I keep a spare recoil spring for all my autos hanging around (or more than one depending...) occasionally when I clean the weapon, I compare the existing spring to the new/spare. When overall length of the existing gets too short in my estimation I replace it. I'd guess that is usually every 3 -5 k rounds on my pistols. Recoil springs are cheap, I don't mind shelling out 10 bucks every few cases to keep my weapons running tip-top. |

If you want to keep your equipment in top notch shape you replace high wear items before they wear out to the point they cause malfunction or unnecessary wear and tear on the equipment. I routinely replace recoil springs at 2000 to 3000 rounds. |
