P938 issues

Purchased a brand new P938 Nightmare Oct. 22. Took it home and cleaned and oiled it just like normal Shot it 3 days later. I could not get through a single 6 shot clip without some sort of issue. Failure to feed, fire or eject. Three other friends shooting with me had similar issues with this pistol. Switched from reloaded and then brand new ammo three times that day. Went through 150 rounds before I had enough.

I have shot plenty of guns in my time and have never seen it before. Upon dis assembly I saw galling, peening, coined metal, interference fits and very uneven wear on almost all moving parts of this pistol. I am positive that I did everything possible to correctly break this gun in. I have pictures of everything stated. I sent it back to Sig for evaluation.

I know I am new here but I am not new to guns or forums. What do you guys think happened? I have complete and total faith that this is, and will be, one of my favorite guns. It just got off to a rocky start. Thanks guys.

P938 issues

I am picking up my new Sig P938 next Friday after 2 1/2 months of waiting. I sure hope I don't have the same issues. I will keep all posted!

Seems odd to have this on a newer 938. I've seen problems with earlier one's. Do you happen to have the serial # handy? Be nice to know if maybe it's an older model that sat on a shelf for awhile.

I'm sure SIG will make it right for you. Just isn't a pleasant experience to go through. I had to send my Nano back for ejection issues. I know how you feel.

Sorry to hear your story. I bought my Nightmare on October 15th. I did what you did.....took it home, cleaned and oiled it, then took it out for its paces. Put 200 rounds of Walmart whitebox through it. Not one problem. Hope they fix your issues, because I agree with you......you're gonna love this gun!

I was an early adopter (July) and it was a mistake.
FTF, FTE, dropping the extended mag, empties coming directly back and hitting me in the forehead, etc. After I sent it back for the 3rd time they sent a replacement 938 made in October and it is much better. I had one failure on a 147gr mag but that was it. Only other problem (same as my previous one) was that it shot high at 7 yards. Sig sent a #6 to replace the #8 rear and now it is ok.
It wasn't a pleasant experience but Sig paid for all the shipping and I am sure it wasn't pleasant for them. I also got an extra magazine out of it but I still wasted a lot of ammo. Based on what I have seen on many different threads/forums there was a high rejection rate on the early pistols.

Btw, the only wear I see on the new 938 is a little bit at the top of the frame rails (blueing worn). Not really any wear.

Just stay on them to fix it right.

I am also curious if it was an early 938 that sat on the shelf...

Both 938's were very accurate.
New one at 7 yards offhand; one full clip:

SN 52A0068XX. Built/Shipped on July 3 2012. I am very optimistic that everything will come out fine. I just hope that it won't take more than one return trip back to Sig. Either way, I am going to make 100% sure that this gun ultimately lives up to the Sig Sauer image in my opinion.

Hang in there. Mine had an August 9th build date and I had extraction issues from day one. Sent it back to Sig and they installed an upgraded extractor, polished the feed ramp and replaced the recoil spring. Turn around time was 3 weeks to the day and it now runs like a champ. Over 500 rounds fired since I got it back without a single hiccup. I now have the utmost confidence in my P938 and never leave home without it.

Just call Sig, with the serial number that can tell if your 938 has the upgraded extractor or not. If it does not have it then it needs to go back to Sig.

If you check the previous "938 tracking" post, you will see serial numbers below 88xx appear to be the ones with these problems. After that number, they started polishing the feed ramp, upgraded the extractor and recoil spring during manufacture. Mine is a 18xxx with a sept bday, and I have not had problems other than when I tried a +p corbon load dbl tapping, that really kicked more than I expected, ending up with a fte. I felt it was more my not holding steady than the gun, I don't use +p due to the excessive kick, using hornady critical defense when carrying with no problems tested at the range.

My Extreme was born 8-1-12 with a very high 88xx. I suggest fill out a detailed letter with any and all info for the gunsmith. I sent mine in for fail to close, and included that it light striked Herter ammo. I stated that all other ammo struck fine and Herter is not the best stuff out there.
Two weeks to the day it came back with a new extractor, recoil, and guide rod.
No mention of firing pin. It now is a sweet shooter and with Herter ammo - all ammo tried.
Also I heard lots of comments on trigger pull. my trigger is very good and I have no need to change it. All around it is a great little gun now. Good thing since I lusted after a 938 since I saw it at the NRA convention last spring.

My 938 Nitron was born 8/30/12, serial 134xx and while I still have FTEs every once and awhile I also experienced a firing pin failure around round 581. Somehow the hammer end of the firing pin mushroomed to the point that it could not move in and out through the firing pin retainer plate at the end of the slide. Sig sent me a new firing pin and all has been well since with the firing pin.

1305 rounds fired to date.

Got it back already.

Gunsmith comments:
Inspected the pistol.
Replaced the extractor and the disconnector.
Staked the slide stop spring.
Function checked and test fired with no malfunctions.

What exactly does the disconnector do? I bought American Eagle 124 grain, Remington 115 and Herter's 115. Been shooting Blazers 115 and Federal 115 up till now. All FMJ. Am I headed in the right direction for ammo in your all opinion? I just want this thing to work. Thanks all.

MRTIMSTIK- How did you get this information? I'd like to find out the manufacture/ship date of my P938 but Sig wants $50 just to tell me. I picked mine up Thurs. Nov. 8th.2012 but was on back order since Aug. 19th. It is a brand new firearm so it's not like they'd have to do a whole lot of digging to find out.

Look at the stickers on the end of the plastic Sig box that the gun came in. Along with the Serial number and Model number is a date.

Find the picture file, right click on the file on your desktop and select EDIT, when paint opens the image, look at the options bar and select RESIZE.
Select pixels and make it 1024 x 768 or less, then select Save

jrprich - Thanks! The sticker was falling off when I picked it up, so I pulled it off and put it in the bottom under the foam!

Going shooting tomorrow for the first time after the Sig performed "evaluation" and fix(?). We'll see how it shoots.

I had ejection problems and slide release would sometimes lock my slide back when is still had rounds in the mag. anther friend of mine had the same issue and after breaking it in it got better. just continue to break in the springs is the only thing i can suggest
