    Installed and shot 50 rounds thru both my 6 round Kahr MK9 mags and they work perfectly. The springs are stiff at first and it was a bit of a struggle to get the base plate on and the last round is difficult to get in, but it gets much easier after a few dozen rounds of cycling as the spring loosens up and takes a set.
    Great design and a fine product. It’s so nice to have that extra round in these single stack Kahr mags.

    Haven’t been able to compress and hold spring to assemble it. Will try again today.

    Love magguts products, have them in several different firearms and all work flawlessly!!!

  5. David Nathanson (verified owner)

    Customer service and initial order tracking was not the best. Could be the influx of orders? Installation was difficult but product works flawlessly.

    Fast easy install works great

    Spring was too big, would not work.

  9. Ken Evans (verified owner)

    Great product. Installed four of them and they all work flawlessly. Moves the Kahr PM9’s capacity a little closer to the Sig P365.

    I trust my life every day to MagGuts. It’s not just increased capacity, but increased reliability and function.

    Works great. Function perfectly. For my purpose, a micro nine in my pocket with 7 plus 1 is much better than the “larger” so called pocket pistols with 10-11 round mags. The extra 7-8 mag rides in my weak pocket. Thank you Magguts.

    Only problem is installation. End of flat spring is sharp and difficult to hold under the floor plate. Kept wanting to slip from under the plate while sliding on the end cap. But after several tries, got it installed. 6-7 spring was a little easier than the 7-8 spring. Be persistent. The new springs are worth the trouble.

    Not sure how to fix the problem. Polishing the end of the spring would make it much easier on the thumb, but would also make the spring slicker to slip from under the keeper plate. I almost filed a small groove in the keeper plate to help hold the spring in place during installation but was afraid that the groove might prevent the spring from seating and functioning properly.

    works as advertised. Difficult for me to install. I used a hobby vise for a third hand and that made it go smoothly. The extra round is worth the cost and the time to install.

    Other than being hard to get the folding spring half into the magazine, it installed fine and most importantly, holds an extra round and functions perfectly and reliably without lengthening the magazine!!!

  17. James Alexander (verified owner)

    Quick shipping, item works like a charm, 100 rounds through the magazine after the Magguts were installed. My CM9 is now even better with an extra round. And still a small compact carry firearm.

    Works well

    The new +1 kit for Kahr 9mm pistols is something that I was waiting for a long time. I bought two units for my PM9’s 6 rounder mags. Installation was a bear b/c the spring is very long and super tough.

    To test them on the range, I fired not only FMJs but also various premium JHPs. To make the reliability test more realistic, I fired each magazine (either 7+1 rounds or 7 rounds) holding the gun with one hand (to make it more prone to malfunctions due to “limp wrist”), and repeated it until I fired all 150 rounds. There was no malfunction of any kind, except that one of the units did not lock the slide open after the last round. So, I had to use my needle nose pliers to tweak the activation tab on the follower to make sure that the slide stop/release would engage positively.

    Great customer service!

    Fantastic! Product received within three business days, well packaged and clear instruction. Difficult assembly required 15 minutes and wearing of gloves but packaging warmed of potential sharp edges. Works as expected, my Kahr P9 Covert now is a 7+1 reliable pistol. Over 200 rounds fired with 0 malfunctions! I’m buying more for my other 5 Kahr handguns.

    Difficulty assembly until customer service sent a work around in response to complaint. Had to have been a known problem. Why not proactively revise videos, send out emails etc? After installation works fine but initial problem means I won’t buy a new product until some time has passed after introduction.

    You guys have an Awesome product and website. Can’t wait until you hopefully start carrying magguts for Diamondback db9 6 round clips. They are desperately needed. Thanks again

    The springs are straightforward to install, and they definitely work as advertised with respect to additional capacity. For whatever reason the follower fails to engage the slide lock and fails to maintain the slide open after the last round is fired. The issue is not associated with all the followers, but I noticed a change in follower design from the first batch to the most recent purchase. The newer followers are the ones I am having trouble with. I hope there is a simple fix.

  34. Eugene T. (verified owner)

    Good design, look instruction !

  35. Anonymous (verified owner)

    Excellent way to improve capacity!

  36. Alexander S. (verified owner)

    Was a little more difficult to assemble than other models. Cycled 300rds through the Kahr with zero failures. Great product.

  37. jack (verified owner)

    Had to tweak the follower a bit by bending the slide stop pad arm up in order to achieve slide lock on empty mag in my older PM9. Other than that, 100% reliable 200 rounds in.

  38. Michael C. (verified owner)

    Functions as designed, not yet tested live fire.

  39. BRIAN BARNES (verified owner)

    Service was excellent, fast shipping. Great product, performs flawlessly.

  40. Ralph C. (verified owner)

    Plain and simple, the best way to add a round without adding bulk!

  41. Michael P. (verified owner)

    After the conversion I ran 50+ rounds through the magazine to assure function.
    Flawless feeding.
    I’m satisfied. Be patient while installing and follow the directions.
