Sig Nut, hello from Florida. I am also a southpaw and have the Sig P938. I have not experienced this issue, but that doesn’t mean much. It very well could be your bird finger causing the problem especially if you don’t experience the issue while shooting with your right hand. My only suggestion would be to keep training and see if you can resolve the issue through practice or just send it back to Sig and see if they can put a stronger magazine release spring in. Good luck and keep us posted.

First, welcome to the site! WRT your P938, we were just discussing its reliability on another thread. My advice is get rid of the gun. I understand they are neat, but in reality they're more of a novelty than a reliable defense gun. Even the majority of those who come to defend it admit they have had some tiny issue with it, which just seems odd to me. I mean why stand to defend a gun you know is known to have issues? Anyway...although these little issues may not be a big deal in and of itself, let me ask you this. Do you really want to put that to the test when you're life is on the line? I know I sure wouldn't. There are better, less expensive options available for pocket guns. Of course, as always, this is merely one man's input. YMMV

No, so sayeth a whole lot of disgruntled P938 owners/former owners. I'm just one guy who heeded the advice of so many who had issues with the gun.

SIG Knows What to DO.

Sig agreed if all else fails send it back and they'd see what they could do. I'm wondering if a stronger mag release spring is available and might help.

You are spot on, a stronger spring will fix the problem. SIG knows it and has the spring to fix it. Call them back and tell them that you are done messing around with it. Get an RMA, prepaid shipping label and send it in for repair; no cost to you.

BTW, what's the build date on yours; should be on the sticker on the outside of the case.

Make sure the plastic pinky extension is all the way down on the magazine tube. It has a tendency to ride up on the mag when reloading or when dropping the mag on the floor.

That was what caused this same issue on my. I'm left handed too.

If this fails, Sig has a fix for the magazine catch.

 

[sig78257]

Had a similar issue, only with the seven round mag and I'm right handed. When CS about three weeks ago I was told they have a new mag catch that is supposed to fix the problem, wanted me to send the gun in to have it installed. Would not send me one or let me buy it as it is so new there was no part number, only the custom shop has them. You can use a 1911 spring, cutting off coils until it fits and is not too hard to press. I bought a calibrated set of 1911 mag catch springs from Brownells and found the lightest one would compact enough to fit and took a slightly harder press to drop the mag and the mag did not fall anymore. Some Sig CS people know more and are better than others.

I respect your opinion, but disagree with the generalization to "all" 938s. Not all 938s are unreliable. Granted, I had the mag drop issue out of the box with my 7-round mag. The 6-round mag has never failed to function properly. Sig replaced my mag catch spring and I have had no further issue with the 7-round magazine. I have had no other issues with the gun in 900 rounds of various target and self defense ammo. I consider my 938 reliable. I'm not saying that there aren't a number of 938s with issues...I'm just saying that there are good ones out there.

It seems the problems were prior to August 2015 manufacture. Most reports of those manufactured after that date are good to go.

That is not true at all. Mine is due back from Sig tomorrow for the mag drop issue. Mfg date of 1-3-17. Sig replaced the mag catch spring AND both my 7 round mags. I haven't heard of them replacing mags for the issue.

 

[DFischer]

Perhaps it's your grip? I Don't see how it can the bird finger. Trigger finger maybe? I suppose if you were gripping it really strongly with the firing hand you could be pressing in the mag release. Or that's what I see holding mine left handed anyway.

Or perhaps it's a mfg flaw as others have wondered..

best of luck!

Sig Nut, welcome from Wisconsin
There are some of us who have had no issues whatsoever, I being one of them. Maybe just lucky.

 

[christak]

I haven't heard of them replacing mags for the issue.

They didn't "replace" my 7-round magazine, but did remove a bit of the black polymer from its base plate where it fits into the gun. I have since purchased a second 7-round magazine and it functions flawlessly as do both my original 6- and 7-round mags.

 

[Scorpionbowl]

Was just on the Sig website and scrolling through the 938 offerings and don't see the scorpion anymore. Possible they have already replaced it? I know they were talking about it.

Another welcome from Wisconsin here.

I also am a lefty and have had absolutely zero issues of any kind with any problems mentioned here in these forums. Maybe I'm lucky like Sigandcz is...i dont know.

I would adjust your grip and see if that works. If it doesnt then the release spring should do the trick.

Us left handers needed to stick together. I have trained to drop the mag with my ring finger as well and have never had an issue with the mag dropping on any weapon because of my grip.

I will back off on my assertion. Internet lore, similar to false news, indicated the MSH/Mainspring and mag release spring issues were resolved in July or August 2015. My apologies for spreading what may be an alternative fact.
