Magguts for CS9?

FoundFather · May 17, 2020

I finally located a CS9 located in Kaliforniastan so I could buy it and did. It was in pristine condition, may not have ever been shot when I bought it:

Very happy with purchase. Kind of wish mag capacity were higher. I have seen very positive reviews on the Magguts kits for the Shield. All the reviews I have seen say they work great and are very reliable. There is a +1 that only changes the internals: Smith & Wesson Shield 9mm MagGuts (+1)

And a +2 that changes out internals and uses slightly extended base plate: Smith & Wesson Shield 9mm +2 MagGuts

I am thinking that the CS9 and the Shield are pretty similar in size and both single stack mags. Has anyone has tried using the Magguts kits on their CS9 mags? If so, how did it work?

The only similarity between the CS9 and the Shield is caliber. The CS has a single-stack magazine and the Shield is a wider, staggered design. Not interchangeable at all.

You could always buy 3913 and 3906 magazines for +1 and +2 capacity and fabricate sleeves like this - Pachmayr Mag sleeves for Kahr MK9 on 3913

Thanks, JS, interesting idea. I sure like the Magguts +1 that doesn't extend mag length, though. If Shield mags are thicker, as GerSan69 seems to suggest, maybe there is some other Magguts kit that would work on a CS9. I sold my Shield so can't compare mags easily. Maybe I just need to order one of every Magguts kit at $23 each and see if any work. I would have thought someone would have performed this experiment already.

Perhaps the Kahr version could be modified to work in the CS9 mag body.

If I want an extra round of capacity, I carry my 3913 or 3913TSW.

I sometimes may carry one of my 8rd mags as a spare for my CS9. Otherwise, it's the 7rd mag carried as a spare.

The CS9 is a great little well-designed gun. Very accurate for the size and highly under rated during its production run. Now you will be looking for a CS45. If you do not already have one, it is only a matter of time.

I have never tried (or heard of) magguts before today, but why do you not have faith in all the other Forums that you have already looked at and found positive reviews?

Personally, if I wanted more capacity than my CS10 held, I would just slip a extra magazine into my other pocket rather than try a relatively new product with all proprietary parts

Because the kits are customized to each firearm and it's magazines. The reviews I have see are reviews for kits used in the pistols for which they were designed. If I wanted to add capacity to a Shield, or an LCP, or a P238, etc. that they have kits designed for, I wouldn't hesitate to buy. But strangely (!) they don't offer kits for low volume firearms that have been out of production for many years. So I can start buying kits designed for other guns, see if I can make one work for a CS9, and then field test over many rounds to confirm reliability. Or I can come on here and see if someone has already done this

GerSan69 · May 18, 2020

Well, I think you have a legitimate question. Those Magguts kits are kinda pricey, though.
Anyway, I think because of the cost, you just need to be careful to experiment with a kit for a magazine that functions exactly like the one you have. I guess you didn't remember that the Shield has what I think they called a "semi-staggered" magazine, so it is indeed wider than a single-stack, but narrower than a true double. I agree that the Kahr might be what you seek, but I'm not so sure if the baseplates are the same.

You know, jsbethel, you have a lot of good ideas. I was way too quick to dismiss the 39 series mag idea. I expect before I'm done I will buy one of those, then a Pachmayr mag sleeve, then a Kahr MagGuts kit. If that all works together, I'll have a 10 round CS9 mag! (Of course, it will make the grip kind of long, so maybe only for a mag change, not for primary carry.) Then I will have to buy a few more, and also experiment with the MagGuts kit in the CS9 mag body for a +1 in the original dimensions. If that works, I will need a few more. You get the idea. My CS9 came with three mags in excellent, maybe unfired condition, and I also had four brand new ones still in factory packaging I bought even before I bought the CS9 so I would be prepared. It never ends...

But thanks for the great suggestions,jsbethel!

To each their own. Smith and Wesson 8 and 9 round 9mm magazines will work with the CS9.

If i were still carrying my CS9, I'd carry an 8 rounder as a second mag and work on my mag changes. The Smith single stack 9mm mags are very reliable. I wouldn't mess with that, but I'll admit on conservative in that area.

To each their own.

18DAI · May 18, 2020

I agree with malph. And I would add that the CS9 is a deep concealment - up close and personal, defensive piece.

Used as designed, you will be out of time before you are out of ammo. With the 8 rounds on board it already has. Regards 18DAI

Now that I understand

I did not come away from your first post with the impression that you were asking about using a Shield kit in a CS9.

It sounded like you were asking how folks like the CS9 Magguts kits

Of course. Look, if I had any sense I wouldn't keep tinkering. I would also have about 90% fewer guns. I guess I'm the only guy on this forum with this affliction?

Nope!

No tinkerers here...

I have a CS40 that I've had for a few years and think it's an absolute dream to shoot. I just bought a pristine CS9 today and can't wait to try her out. These are great little guns.

Congrats, Ray! The CS9 is agreat little gun, and I think well suited to 9mm. Philosophically, I think that the size of the cartridge should be commensurate with the size and weight of the gun. On the other hand, evn though i love .40, if I got my hands on a CS40 I would probably start planning it's conversion to 10mm right away. I know 10mm is too much for a gun that size, but sometimes I just can't leave things alone.....

Lol, thanks. I'm looking fir a nice 3rd gen 10mm also. I've seen the conversion threads here and while I think it's a cool idea, I think the 10mm round might be a bit much for the little gun.

Very nice guns you got there,Rick. Mine is the all-black version. How common are these? I've looked all over online and info is scarce.
