    Excellent product. Well designed and very well made. Instructions were the only downside. Difficult to follow and poorly worded. Videos did help a lot, but shouldn’t be necessary.

    I returned the MagGuts RMA # 1434 on Sept 2, 2017 and still have not received my refund. Thought maybe Hurricane Irma got it.

    I purchased a SW .380 Bodyguard and Immediately started looking for an option to add an extra round or two without taking away the concelability that I bought the gun for. I found mag guts and thought I would give them a try. I could not be more impressed with the quality of materials and ease of installation but the best part is it doesn’t change the profile of the firearm at all. I have fired the pistol several cycles with the new mag guts installed and it has been flawless and have even had a couple of people on the firing line notice that I was getting an extra shot. I told them about the mag guts and they were excited to see if they were made for their firearm too. Thank you for making such a high quality innovative product. Keep up the good work. Dan

    Installed subject MagGuts in two of my EDC BG380 mags. Have had zero failures in approximately 120 rds after keeping the mags fully loaded at all times for the last couple months. Last round slide lock is functioning with no problems. I’ll install on any additional mags that I acquire. Thx.

    Thomas R. (verified owner)

    The parts were great! Everything went together smooth. But when I put the clip in the springs were too tight and there wasn’t enough room for the slide to be able to slide back. It doesn’t have enough room in the clip for the bullet to depress enough for the slide to slide back. I’m sure I didn’t install it wrong. But that’s my only complaint. I’m hoping that after having it full for a few weeks it’ll settle in and the spring will loosen and provide more room in the clip.

    I purchased two of these before they changed the follower design. They never worked correctly. I have attempted to get Magguts to send me the new follower to correct the problem but they refuse to help. I even offered to buy the new followers and I was told they wouldn’t sell just the followers. I would suggest not to deal with magguts

    This is my second review. The first one was deleted. Kit did not work in my BG380. The slide locked back with a round still left in magazine and then didn’t lock on the last round. Magguts won’t send me the new followers to fix my problem.

    I wanted to wait until I could shoot my BG with new MagGut mags in it. This is the third set of MagGuts I have purchased ( Glock 42 & 43). This was a little more difficult to install, The instructions were great and as long as you followed those instructions, everything went well, A great addition to my BG, I am very happy with all my MagGuts addition to all my little pocket pistols, THESE PRODUCTS ARE WELL THOUGHTOUT AND WELL MADE, THEY WORK AS ADVERTIZED!

    I have the Magguts installed on a Smith and Wesson bodyguard .380. I’ve had no failures with it through 500 rounds. Slide holds open more reliably than with factory mag springs which don’t work well out of the box. Would like to order another Magguts set.

    This is my second – I bought the first to see if they work and it worked so well I outfitted my second mag with one. There’s some serious engineering that went into the design. Being able to add an extra round without changing the size or shape is great. I’ve put about 200 rounds through wach magazine with no issues. Installation is a breeze if you follow the instructions and get all the parts in the way they are supposed to be. It’s not hard but like any mag, some parts will fit backwards. Pay attention and yours should work as well as both of mine do. 7+1 is a worthwhile enhancement to me.

    I like that I’ve added extra round to each of my pistols. I’ve about 60 rounds and have not had a problem. I liked the kit for the BodyGuard better and it was easier to install than the Shield. Liked wire spring plus strip (wider spring). As opposed to only the strip spring for the Shield. So far so good

    I just recently purchased a brand new BG .380 and it would not hold the slide open on the last round. Nor would it stay open with just an empty magazine installed. Smith and Wesson has a serious issue with the cheap plastic orange followers they install in BG .380’s. I have three Smith and Wesson magazines and none of them work correctly. This product instantly corrected the issue. Not only that, it also correctly pushes the magazine out when engaging the magazine release. Aside from the benefit of adding an additional round, the gun functions 100% better. MagGuts is an amazing product. If you’re having similar issues with your BG, this will fix it! I’m getting ready to purchase another set for my second mag.

    Well, I bought two and they installed easy enough and they had the extra round nicely. I had a concern that part of the bottom plate rested out of the magazine. I guess that tip that fits the bottom piece was supposed to hold it. My concerns were validated on the first day at the range. It functioned well until I practiced mag changes. Somehow that tip on the base plate worked its way out of the bottom cap. Not surprisingly, rounds would not load. I took it apart to fix it and in true spring fashion, stuff went everywhere and I lost they cup between the two springs. Maybe me it will be good as long as it does not roll around in your pocket. But I think I will go back to the factory spring. 7 rounds I have faith in is better than 8 rounds I hope work.

    Overall pretty good product – provides an extra round with no increase in magazine size or loss of functionality. I ordered 2 kits, 1 kit fit great but the second would not allow mag to seat in loaded pistol. I emailed Corso, they replied quickly with troubleshooting tips. These did not help, so I requested a replacement, which was sent promptly along with a prepaid return address label (you might consider opening your order envelope carefully just I case you need to reuse it). Replacement worked fine. Pay careful attention to assembly instructions, also there are some videos on YouTube that might help.

    I’ve used the bg 380 +1 conversion for years, but one I just put together flew apart when I loaded it. I wish the bg380 spring was as robust as the new shield design. Would make me more confident in it.

    Super easy to install. Deciphering a picture of a spring can be difficult, but if you get it wrong and it doesn’t work, just flip it around the other way. If you need more help than that, there are several YouTube videos to watch. I put a bunch of rounds through without a hiccup. I also tried dozens of times to make sure it feeds properly while racking. It feeds perfectly, even while slow racking, unless I slow rack with the last round in the magazine, but for what it’s worth, even the factory magazines jam on that last round. It was never meant to be operated that way anyway. I just always like to really test things out by going beyond the scope of normal operation. Bottom line, if one extra round in your magazine is worth the $23, don’t think twice and grab one. I look at it this way: If I ever needed that seventh round after I spent my six and did not have it available, there isn’t a dollar amount I wouldn’t pay to have it in that moment. It’s a no-brainer for me.

    I purchased the Ruger LCP II and the S&W Body guard Mag Guts. Both did extend the Mag capacity by one round. But both have poor design on the lift plate (the plate just under the round). on both you cannot insert an empty Mag into the gun for the lift plate cocks and jams before it inserts. The body guard lift plate jumps out of the housing an requires carful positioning to load ammo into the mag. Once the mag is emptys it is a 50/50 chance it wild lock the slide back. I believe it is all in the lift plates and Mag guts needs to rework there design. also on My Body guard this mod worked with my oldest mag but the bottom base plate would not latch on a new 2018 OEM mag.
