Hello, was cleaning my 40F this morning and noticed a crack right down the middle of the lower, front of frame ... the weapon is done

I have a buttload of 15 round magazines for this pistol and need to know, without a doubt what other Sigmas these magazines will fit. I'd love to grab another Sigma (newer, with rail) and have these magazines work.

Thoughts and thanks

They fit ALL Sigmas 40S&W or 357SIG

HOT DIGGITY !!! Cheers Sir

OK ... next question, does that include the SD's ??? Thanks

The only fit issue I have seen is some of the early mags have slightly thicker base plates that prevent locking into SDs. I cured mine by taking the base plates off and sanding some clearance on the tops of the baseplates--or you could put SD baseplates on the mags.

Excellent OKFC05, I appreciate

WELL ... here I am again, confused (natural habitat). Research is showing all these 14 round options for SD40VE pistols. Even looking at a new SD40VE shows them as "14+1" ... the buttload of Sigma 40F mags I have are all 15 rounds (15+1). So is the deal that these mags will fit, will work but because of different baseplate my mags will appear to "stick out" not have a flush experience down there? Sorry Gents ... run a small business (broke as hell, COVID ain't helping), former USMC and just need to get armed back up in the best and most economical way ... since I already have $1000 worth of magazines for these pistols. CHEERS

The early Sigma magazines had a slightly longer body.

JSBethel ... I see the difference (great pic, thanks) but will my buttload of Sigma 40F 15 round (factory) mags both FIT and FUNCTION in a SD40VE pistol ??? Really appreciate

If youve got a local shop that carries the sd40, maybe you can see if they will let you test fit one of your empty mags?

I thought of that, can't find one locally. Been taking chances all my life, let's see how it works out. I ordered one from PSA last night, I'll let everyone know in a week or so. Betting I I can take a few of my kydex holsters for the 40F and "heat gun" them into submission (LOL) as far as fitting the new SD40VE.

I can't speak to the SD line, but the Sigma VE line could take the original F model mags just fine. I bought my VE back during the ban and all I could get were the F model mags. They are slightly extended, but only really show it in the back. The floor plate is flush on the sides with the bottom of the gun.

The SD mags are supposed to be able to work in older VE guns, so it's safe to assume the mags are compatible.

I have never shot or carried my 40VE with anything but the 15 round F model magazines.

Pistol arrived yesterday ... all 20 of my 15 round magazines from Sigma 40F fit and fed rounds. Sure, the bottom plate a little off ... who cares. Not range tested, but it appears to be good to go. THX

Did you check with S&W on the 40F?

Steve912 ... I just sent the pistol back to S&W, I have not heard back from them yet

Sweet! Did they give any indication of it being a known problem?

I have not heard back from S&W yet, I do know that they have received the 40F

Saw a SW9F on GB yesterday, with similar cracking, all around the s/n plate.

SW40f 15 round mags will fit just fine in a sd40ve. Are you willing to sell one of your 15 round mags? I’ve been looking for one for months

When I first tested to see if 40F 15 round mags would fit, I inserted and removed them empty. Today at range, I was inserting 40F 15 round loaded mags with slide open, then releasing slid to chamber. Got home and went to insert a loaded 40F 15 round mag into the SD40VE with the slide home and found an "issue" ... you have to slap the mag like it insulted your Mother's coleslaw to get it to seat. I tried a few and same result. I'm borderline comfortable with how hard you have to smack the 40F 15 round loaded magazine so I'll have to research and think about it more.

Thoughts ???

I use Sigma 40F 15 round mags exclusively in my SD 40, no issues. Love the extra round.

I own a 40F, 40V, SD40 and use them all interchangeably. My brother has the 40E and uses them in his. I also use the 9F mags in my SD9.

It is just a bit tight with where the base plate hits the bottom of the frame. I think someone else already mentioned taking the base plate off and sanding the top of it so it clears the bottom of the gun. Should fix you right up if it bothers you. Or you could sand the bottom of the gun where it hits, but I prefer modifying the mag over a gun.

As for holsters, most of the ones I have tried, the Sigma, SD and M&P guns fit each others holsters. I can see maybe if one is tight it might be an issue with another model, but mine all fit fine that I have tried.

FIXED ... I took the base plates off the 40F magazines and then ran a sander across the tops of the base plates to remove enough of the baseplate that it would easily seat into the 40SD without any slapping. Of course I stippled the plastic base plates ... here in Tampa, everything sweaty, easier to grab. The 40F is on the left, 40SD on the right

What is the rest of the story on the Sigma 40? Did S&W replace it? Repair it?

Rosewood

I have a SW9F and a SD9VE. The magazines are interchangeable between both guns without a problem. Don't even need to modify thr SW9F floor plate.
