Handgun Service Interval Thread

[eternal24k]

I was wondering if it would be possible to get a thread with the different service intervals in one location, I often find myself wondering with different platforms and thought this might be helpful. Maybe I will compile a Google Doc "Chart" later. Below is an example of what I was thinking, sources are recommended, and my example might not be the best since Sig officially only states you send in every 5k, but I have seen these numbers many times and have thus felt comfortable with them. Anyways, everybody could post what they have I can add it to this post.

Firing Pin Spring: R; 3000

It's a good idea. The only caution I would have is for folks to post verifiably good information. If you're a trained armorer and you have all that info handy and don't mind sharing, please do so. I'd just like to make sure we don't end up with a thread of wild-ass guesses. :D

[RancidSumo]

Great idea for a thread!

I would be very interested in seeing this info for a 1911 and M&P if anyone has it handy.

[TheSmiter1]

Good idea. I'd like to know the HK P2000/sk, P30, HK45/c, M&P, and Glock Gen 3 & 4, large frame and small frame.

I absolutely agree, it is surprising how hard it is to find this information. My Glock armorers guide from the 90s and both my older Sig armorers guide have nothing regarding intervals :rolleyes:

But hopefully with the combined knowledge base on this forum we can put something together (I can't even imagine such a thread on TOS)

On Sigs.

It's not in the armorers manual but replace the solid FPPP every 10,000 rounds. I've seen quite a few break before 20,000 rounds due to dry firing.

Makes sense since roll pins need to be replaced.

Bump,
maybe some XD, M&P, Glock, Beretta armorers in the house?

[tylerw02]

Good thread. Thanks for the post! Would love to see this for other models if armorers are willing to share.

I haven't been to Glock school for a couple of years, but every other time I attended they had no service intervals noted on stuff like springs.

From personal observation of broken parts, and other issues, I swap out the recoil spring assembly on my Glocks at no more than 3000 rounds. If I was still shooting .40s I'd go 2000 to be safe.

I have been known to show up to a course like the TDSA AP-1 where I can burn up to 2000 rounds, shoot for the weekend and at the end throw the recoil spring assembly in the trash. I install a new one and test fire to be sure, then go home with a warm/fuzzy.

This might seem a bit much, but back in the day it was common for folks to have to swap recoil springs on a 1911 every 1000 rounds.

$5 is cheap insurance.

I'd personally swap out all of the springs in the gun at 10,000, if I didn't do so earlier.

If anyone wants info on the S&W 5906 type pistols let me know and I'll dig out my manual.

So how did they recommend determining when springs needed to be changed?

Thanks

While I respect Mr Yam and his information is clearly logical and well thought out by his experience, I feel a lot of these replacement schedules are a bit of fuzzy math. There are original GI 1911's with a bajillion rounds thru them with all original parts and still functional and sigs that are 5 years old that when inspected need major parts replacement to be up to standard. The confusing thing here is that a gun rebuilt to "in spec" might not function and some that are so beat they look like scrap iron chug on.
The 1911 got its reputation for reliability in severe conditions with very heavy often abuse use with little or no regard to parts replacement schedules we try to adhere to today.

[eternal24k]

This is about preventive maintenance, it matters not how far one can go without doing it.
Just becauseI could probably go 50,000 miles without changing my oil or servicing my car doesnt mean I should or that the manufacturer is in the wrong for providing a maintenance schedule.

+1 to that!

would love some Glock, M&P and/or any other info

[SERT103]

I know this isn't as specific as most of you are looking for the Glock pistol, but this is all the information listed in the scheduled replacement parts section. I will get out the MP armorers manual next.

[SERT103]

Just looked through my M&P armorers manual and it didn't contain a scheduled parts replacement section. I don't even remember the instructor suggesting parts replacement at certain intervals other than the RSA. Mostly "inspect and replace if worn or damaged".

[Magic_Salad0892]

I remember reading that Glock springs should be replaced every 5k rounds.

Glock CS Rep told me that the Gen4 assembly should be replaced every 7.5k rounds.

FWIW: I replace ALL springs in my gun every 5k rounds. Firing pin safety at 10k.

[ShipWreck]

I always thought that the recoil spring on a 5" 1911 was every 2000 rounds.

[John_Wayne777]

I always thought that the recoil spring on a 5" 1911 was every 2000 rounds.

It depends on the weight of the spring. The "standard" 16 pounder is pretty much done after 1,000 rounds of 230 grain hardball. 18 and 20 pounders can go longer. I generally changed out the heavier springs every 3,000.

[Iraqgunz]

The last time I was at Glock I believe that they said change the recoil spring assy. at 5K. I don't remember there being numbers for the other stuff.

For all the Gen4 recoil assemblies?

The ''01'' assembly (first time I had a Gen4) is what I was referring to.

I'm not 100% sure the numbers would change based on weight of spring.
