    Took a chance and purchased for one of my glock 42 magazines, and after installing (5 minutes) and range testing (100+ rounds with no ftf’s), ordered additional MagGuts upgrades for all of my Glock 42 factory mags. Also added a +1 floor plate and was able to load the mag with 8 rounds. Probably fired 300 rounds through 5 mags without a single failure. Almost rated at 4 stars because they are pricey, but I knew the cost going in, and they work great. So…. 5 stars. B.Short

    I love the concept of having an extra round in the magazine. Unfortunately it comes at expense of giving up reliable feeding. My factory mags run perfectly but the ones with the mag guts follower jam constantly. I am going to put the factory followers back in.

    Mag guts products came highly recommended from a highly trusted shooting buddy. I was a bit skeptical at first modifying a stock glock magazine especially changing the follower, however I must say that Mag Guts has truly done their homework on these products. I installed mine and proceeded to torture test 2 magazines with hundreds of rounds. My findings are that these meet or exceed the factory followers. Not one issue in hundreds of rounds! Look no further if you are wanting to add that additional round to your factory magazine.

    I recently purchased a MagGuts’ kit for my Glock 42 6 rounds standard magazine. Not only has increased the magazine capacity with an additional round, but it has allowed the overall size of the gun to remain small. This in turn has kept the conceal characteristic intact, reducing the printing possibility to a minimum! It has function flawlessly!

    The MagGuts +1 kit for G42 works 100% after extensive range testing using 3 magazines. I also tried combining the MagGuts +1 kit with Scherer +1 mag extension. I had to modify the spring retainer base that came with the Scherer extension to make it works with the MagGuts kit. This gave me a +2 capacity and it also works 100%.

    Simple install. Worked flawlessly from the start and have run at least 20 mag refills through my G42 with no F2F. Attempted to use in conjunction with Strike Ind. +2 extension to get a total of 9 in the mag… the front of the follower catches on the lip of the bottom of the mag when trying to install 9th round. Have not yet attempted to modify the bottom of mag body to see if that will allow it to clear. MagGuts is a great product for +1 ultra concealability.

    Received in just a few days. Purchased three sets for three Mags. Yes they work well for one extra round. When adding a plus one finger extension to make eight, hard to add that extra round. Tried with no Mag Guts kit and only the plus one extension with original Glock spring and follower and got one round extra. Does not work with plus one and Mag Guts kit.together, I was able to load eight rounds with both kits on the mag but only with brute force, using a mechanical mag loader. Thing is that if you plan to add a finger extension plus one for your pinky support that cost only $9.95 plus tax no shipping, local store has them.. Or not adding finger extension adding Mag Guts for one round for $17.95 plus tax and shipping. .

    Normally I like these devices to add a round, but one of the two I bought has been very difficult to work with. Please note the difficulty is only when using it with a plus 2 Hyve mag extension which is Not recomended, however, the other one did work with a like extension. In a standard magazine, both add a round perfectly.

    I decided to replace my Taran Tactical plus 1’s with aluminum pinky extensions. The Magguts spring system is easy to install and has functioned perfectly. Between the price of the Magguts and the pinky extension it is about the same as paying for a new Taran Tactical but now I can get a full 3 finger grip and still have 7 plus 1. So far so good.

    Works as advertised on my Glock 42. Took it to the range and had no feeding issues at all. One extra round with no extra size, Glock should have done this from the factory. Shipping was also nice and quick. I’ll be back for more of these.
