Just bought a P938 for the wife. Thanks for the heads up.

You should get some sort of public service award for posting that info. Thanks a lot. Now I've got to go and check my P938 edc.

I just checked mine and it's going to become part of the maintenance routine going forward. Thanks for the info BT.

As he mentions, this is a "known thing" around P938 circles, and there are lots of discussions about it over on the SigTalk forum. Some folks use Locktite, but others have recommended JB Weld instead, which is what I used and have not had any issues. I do check however every time I clean the gun.

Makes sense.

Very helpful!!

I was not aware of this till now. Mine is presently GTG and I appreciate the info!

You can use locktite or JB Weld either one will work for awhile. Then the guide rod will break at the part where the threads go into the end piece.

All of the 938's broke at some point at the range I worked at. Of course, this is with thousands of rounds through them.

So, this is a known defect that can disable your firearm without warning and Sig has not issued a recall. Wondering what they are waiting for- a fatality?

Great question. It is a lot less expensive (apparently) to make the two-piece design and uses less raw materials. There were some rumors for a while about a impending redesign release of a one-piece guide rod, but those rumors never panned out as far as I know. I have probably 2,000-3,000 rounds through mine, and have not had any issues.

They also had an issue a while back with the MSH assembly, and I was getting some FTF and FTE issues. Sent to Sig and they installed the new MSH, and I have not had a single misfire through the weapon since. Although it was a bit rough for the first 2 weeks with the MSH issue, it has been 100% reliable ever since. I carry it every day, and I have no problem depending my life and those I love on it.

Yoy don't have to take the P938 apart to check the guide rod. It's quick and easy.First: UNLOAD THE GUN. Second: CHECK TO MAKE SURE THE GUN IS UNLOADED! Finally, lock the slide back on the UNLOADED gun. With a pair of pliers try to unscrew the exposed guide rod. If it will, it's time for the loctite or JB Weld. Don't forget to clean the threads on both pieces first.

Anyone make a one piece rod for it? You know, after market stuff.

Excellent. Thanks for that. I will check mine for sure on the next cleaning.

BT thanks for the link.
That is disappointing news, as a 938 Extreme was on my short list of guns to buy.
I think I will be skipping it all together now, I don't want to have to worry about my guide rod shooting out the front of my pistol, even though Sig will send a new one, who wants that hassle? I don't.

I understand your worries, but honestly, it is a very rare problem. The P938 is supposedly the best selling Sig on the market (internet rumor, I have no official proof), and there are many 1,000's of them out there running just fine. I have never had an issue with my guide rod, and I have about 3,000 rounds down the pipe.

Thanks for the reassurance. I will do some more research before completely making up my mind.

I love mine. The only problem I have had is, it does not like hard primers. I would think normal inspection while cleaning would prevent parts flying out of it while shooting.

Okay.....this is really embarrassing, but my guide rod was really loose. About halfway through the threads!!! Thanks for the thread BT!!!!
