MagGuts M&P Shield install and review

Adding life and rounds to a gun that has become very popular for its concealability. The problem with small guns has been their limited rounds for the gun. Sig 365 has challenged this positions by creating a small double stack and increasing rounds. This is a way to add rounds and not buy a new gun.

the spring edge has to lock into the base plate pad

[@tires2burn]

I tried for a hour to install the mag guts spring and could not get it done. Sent it back. Nice to see I'm not the only one that had trouble with this.

[@geoff_tac]

No joke..it's gratifying once it's in there. 11 rounds in a single stack has it's uses.

[@surfside-hj2ue]

Are there any companies that sell a 13-round extension?

[@TheMegamanpr]

Had my first malfunction with one of these the other day. The follower got stuck in the middle of the magazine preventing the zigzag spring to push up the rounds, still had like 4 rounds left that were not fed into the chamber

[@cinca0989]

I've had the Magguts +1 system in several 7 and 8 round magazines for over 3 years now. I didn't want anything with a larger footprint than the factory and the +1 kits were perfect for me. I ran 500 rounds through each before relying on them as my carry mags and I've got well over 2K rounds on each without a single malfunction at this point. I'm very happy with my purchase and while it wasn't the easiest install, it certainly wasn't difficult. I believe there's a V3 out now if anyone is interested in an improved version.

[@joehardway]

Tried'em on'a Shield 40, in conjunction w/Strike Ind +1 ext, which, of course, neither mfgr supports, so I was on my own. Frequent failure to go into batt, and the follower has gotten stuck, a time, or 2. To makit more complicated, I never actually shot my Shield, b4 fiddlin w/tha mags, so I don't even know, ifit woulda run right, outta tha box. Need to buy new factory mags, and establish some baselines...

[@Kenarew]

You cussing over the sharp spring gave me a genuine chuckle.

[@thecadillacoftokyo8788]

What would happen if you used a +2 base plate with the spring? Would it become a 12+1 magazine?

[@notmyrealname3462]

no, 11+1, 8 rd mag, +1 with spring + 2 base plate

[@joehardway]

I added Pearce +1's to both my .40 mags, but, livin in tha PRK, I wanted as much extra bang as I could get. Emailed Magguts, and they said they hadn't tested with any other extension device, and I was on my own. So! Everything that follows is totally without Magguts's blessing, and should not be construed as a real review. Decided to go for it! Install went ok, but tha Magguts springs def feel ali'l "squirrely", and, due to their sharp edges, they don't exactly feel smooth. At 1 point, I was loadin with my Maglula, and pushed down to ensure it was full, and the follower rolled, in tha mag, and got caught. I got it out, but that waza pretty big red flag. Also, tha rounds seem to be "dippin" abit, in tha 7rd mag, whose capacity has been increased to 9 via use of Pearce extender and Magguts. The case rims are catchin on tha front lip of mag, when I push rounds outta tha mag w/my thumb. Rounds seem to eject ok when rackin slide, manually, but it also seems much harder to rack, in this config. Considerin removin some material, but I wanna make sure this won't allow tha rounds to dip even lower. Have yet to do any live fire testing. Fire closures in SoCal, n I hate ranges. Hopin for some reasonable temps intha desert soon... Wish me luck! 🤞

[@donvape336]

Thanks. I just got this instead of buying another gun. Can't wait to be frustrated at the install.

[@geoff_tac]

I have been happy with it, I plan to do an update video on this. I took some video from the range, I just need to edit it. Let me know how you like it. I did email them to see if they would be willing to let me evaluate their newer one and no reply.

[@johnniewasr5740]

Why didn’t you just wear some gloves to protect your hands from the sharp spring?

[@geoff_tac]

I didn't think I could get the fine manipulations required to get it to stay. I did ok, no major trauma, but you feel it.

[@sneak916]

I prefer the magguts +1 on the 7rd flush mag. It’s still perfect for conceal carry

[@tommylor9293]

Will it work on the 7 round mag?

[@crabbyturtle1594]

Since you've owned these over a year now, how have the MagGut springs held up? I put the plus 2 on my factory 7 and the plus 1 on my factory 8 giving me two 9 round mags.

[@geoff_tac]

Great question, I did a follow up video for people curious about that very question. You can see it here. kzbin.info/www/bejne/e3mko4t6Z6yAfLM

[@bryanfisher9077]

Have any issues with mags ejecting like they don't throw mags out as factory 8 or 7 round mag?

[@geoff_tac]

Not at all

[@bryanfisher9077]

See mine eject and everything but they don't eject has hard as 8 round or 7 round mag like they don't kick out as fast

[@geoff_tac]

@@bryanfisher9077 I was at the range today and it worked flawless. Ejections don't sound like a magazine problem, the cartridge has already entered the chamber and is be extracted. It hits the ejector kicking it out of the gun. I dont see how a magazine would be responsible.

[@bryanfisher9077]

Its almost the the mag sleeve is too thick after sanding the sleeve its fine now

[@brandensoutdoorb-channel8084]

The mag is a 10 rounder. Not a 10+1.

[@geoff_tac]

The mag is 10 rounds, the gun becomes 10+1. If I misspoke thank you for clarifying.

[@robertpickard304]

After some use. Is it holding up?

[@geoff_tac]

Yes sir, if you read the comments here, there were varying experiences. Mine has been positive since getting it and I carry it almost daily. I have had zero issues with it.

[@alickswiden71]

I've actually been having the same issues with mine. Mine is a 40 and I ordered as such, and I was very careful on install. But since I put it in I have noticed too many times it has jammed or failed to eject the spent shell out and I ended up dry-firing on a used shell. This is my CC so definitely not liking questionable reliability... I hope there's just some other explanation I don't know about cause I really like the idea of having one more round per mag than how little the 40 does

[@alickswiden71]

cause lets be real, I could have just saved up another $100 and gotten a G19 which is larger but holds a lot more and wouldn't end up worrying about feeding..

[@ozysjahputera7669]

I had 4 8-rd Shield mags modified with the MagGuts +2 kit (Gen1). They did not consistently lock the slide back after the last round. I think the Z-spring does not provide enough tension for the follower to push the slide stop up to lock the slide back when the mag goes empty. So I moved the MagGuts +2 kit to the 7-rd Shield mags. Since the 7-rd mag is shorter the Z-spring is compressed more, thus providing extra push to the follower. The 7+2 mag worked better in locking the slide back when it goes empty. However, after 18 months being used for daily carry the 7+2 modified mags are now losing their ability to lock the slide back after firing the last round. I think the Z-spring is losing its strength much more quickly than the standard coil spring. So I now just use the extended floor plate and the plate lock from the +2 kit in the magazine with the factory follower and spring. This combination gives me +1 capacity with much higher functional reliability. I think the Z-spring is just not a suitable replacement for the factory coil spring in terms of tension and long term wear.

[@geoff_tac]

Thanks for the comment, I have heard this from other people as well. I have had zero problems with mine and I test it periodically. Its in my carry gun so I don't always shoot this one but this kind of information is helpful to others.

[@ozysjahputera7669]

@@geoff_tac I usually practice with my carry gun (Shield) every other month. So I noticed right away when these mags with +2 magguts started failing to lock the slide back when they go empty. I contacted MagGuts about this and their reply was simply "it should work". They do not stand behind their product in any long term sense. Once your 30-day period is up then you are on your own. Since I am stuck with 4 Z-springs and 4 metal followers, I am trying to see if using them as a +1 kit in a 7-rd mag will work better. So I ordered a +1 lock plate from MagGuts which is designed to work with the factory flush floor plate. My logic is, the Z-spring may get more compression when installed in a 7-rd magazine with standard flush fitting floor plate.This may make it more reliable in terms of locking the slide back. Once I got the lock plate I will give it a test and share the results here. But for now, I would stay away from the Z-spring for long term use if you want complete functional reliability. In my case, 18 months of having these Z-spring compressed in loaded magazines was enough to reduce its tension to cause slide lock back failure in all 4 magazines.

What site did you order the kits from?

[@Redskin4ever]

I must be doing something bad wrong. Installed the +1 and the +2 in my 7 and 8 round mags. The mags will not lock up in the gun with the slide closed, hence, no plus 1 in the chamber. This is an absolute waste of time and money. Worst part, can't even find a phone number for Corso Inc. In Cody Wyoming.

Been using the Magguts +2 in my 7 round magazine for several years. It's great having 9 + one in the chamber with no real increase in the length of the mag, maybe a ¼". I have never had a malfunction with the Magguts either. Well, haven't had any kind of malfunction with the Shield in the last 2600 rounds. Its been 3 years or so, but I don't remember having that much trouble installing it.

Still works fine, loaded 24x7. I use it at the range periodically and still functions through the entire magazine.

[@briansimas6003]

I am using the factory baseplate that supposedly adds 1 round. There is no way in hell an 8th round is going in there, and yes it’s installed correctly. My take on it, is S&W would have built the shield this way if it were meant to run it. 10 rounds in a subcompact is a very marketable thing.

[@almostontimehero5415]

I cut my thumb on that mag. Getting that 8th round in there is tight. Just man up suckka, after 1000 rounds and leaving it full for a few months it will soften up.

The shield is a gread little pistol,and when they came out there weren't a lot of options in this form factor. Now the 365 with its double stack form factor its an excellent pistol but it didnt exist when this was made. This is a way to get a little more life out of your Shield.
