The schedule doesn’t mention the solid firing pin positioning pin (FPPP) used in SIGs with one-piece stainless steel slides like the P229. The retention pins mentioned above are the hollow roll pins use in two-piece carbon steel slides with separate breechblocks (e.g., the P225, P228, P245, and older P220 and P226). The reason for replacing them so frequently is reportedly that they loosen and that reduces the rigidity of the slide assembly. That in turn results in the slide’s flexing when fired and increases stress on the frame rails. One-piece slides are not subject to that problem.

Although the solid FPPP isn’t mentioned in the schedule, it must be preplaced by default every 20,000 rounds because that’s when the other parts of the slide assembly are replaced: the firing pin and its spring and the safety lock spring. The FPPP is not reused.

Actually I asked this question yesterday (03/02/10) during the LE SIG Armorer Certification (Re-Cert) Class in Phx, AZ and was told the solid FPPP used in stainless slides needed to be replaced every 3 years/5000 rounds. The instructor said since we were in a dry climate we could get away with doubling that; however, the official answer was 3 years/5000 rounds.

He said a major reason for replacing the FPPP was officers repeatidly dry fired their weapons without snap caps. He said that snap caps were really recommended in SIGs to ease stress on the FPPP.

My FPPP was showing some wear from dry-firing (marking with texture) after just a couple hundred dry-fires (at most). I can agree with that schedule.

Also, would love mantenance guide!

The agency who hosted the LE SIG Armorer's Re-Cert, who is 100% SIG with a lot of officers, even mentioned that they'd seen a number of the broken solid FPPP from dry firing in new guns. Those solid pins are difficult to remove without a press, unless you don't mind beating up agency slides.

The instructor said the new spiral pins are easier to remove and should be coming on the new pistols. Just as a side note, the original double roll pin can me removed from any direction, as apparently can the new spiral roll pin. Those solid pins have to be put in from left to right and removed right to left. I have seen the new spiral pins on some of the new P229s around out office....and they just don't look right to me on a stainless slide.

Can someone explain exactly what that is (and maybe post pics)?

Thanks!

Older SIGs with formed and welded carbon steel slides had removable breechblocks. The blocks are held in the slide with (hollow) roll pins. Because it's important that the breechblock be held in place very firmly, the roll pins should be replaced after 5000 rounds.

SIG has now gone to roll pins in stainless slides as well but their only function is to retain the firing pin and safety lock mechanisms, so I don't know if the 5K replacement schedule applies to them

Maybe I missed it, but I didn't read anything about the AGE of the springs or replacement parts as opposed to the # of rounds.

I ask because of all the recent ex-police guns that have been hitting the market.

Some of these are early 80s and, while not shot alot, I'm assuming that it would be a good idea to replace certain parts just as a "while you're there" kinda thing.

Sort of like replacing the fluids in a car thats sat for a while.

What would be the recommendation for one of the ex-police P6's or P228s that have low rounds but long years?
