  1. Carlos C. (verified owner)

    Great, easy to install and have been to the range twice since I added it to both magazines and no malfunctions either time with over 200 rounds!

  2. John L. (verified owner)

    Love the product. Have them for every pistol you make it for.

  3. Edward M. (verified owner)

    Didn’t take long to install and gave me one more round.

  4. Brad S. (verified owner)

    Worked well like it

  5. Ralph C. (verified owner)

    I have 3 Sig P238 magazines, 1 6 and 2 7 round. I wanted to increase my carry capacity and found MagGits in an internet search. They exceeded my expectations.

  6. Tsachy H. (verified owner)

    I love it

  7. Chad M. (verified owner)

    I recomend this company highly. Their product fixed a feeding issue i had with a brand new p238 and I got an extra round. Worth evey cent and more.

  8. Patrick S. (verified owner)

    I’ve installed two of these and put almost 500 rounds through them flawlessly. Very impressed, you will be too.

  9. Devin (verified owner)

    Fast shipping, easy to install, and work perfect

  10. Mark W. (verified owner)

    The magguts work absolutely perfect. Installation was simple, and they feed my pistol just like a stock mag. I’ve only ran a few hundred rounds through them so far but I trust them enough for my edc. I’ll buy from them again for sure. My only gripe is shipping from south Florida to central Florida took a week. No fault ofMagguts, just the USPS at there finest.

  11. Carl B. (verified owner)

    The conversion kits work great

  12. Robert M. (verified owner)

    Even one extra round can make a difference. I watched the video and installed in a matter of minutes. I will be ordering the one for 7+1 for my other 2 seven round mags. Great product seems well made.

  13. Ismael D. (verified owner)

    The 7 rounds fit.But they fit very tight.Not easy to load the magazine

  14. James K. (verified owner)

    Good product. Does what it says and does not compromise function. The installation video is also adequate.

  15. Roger M. (verified owner)

    Works great. Wish I new about them sooner.

  16. Muzammil Q. (verified owner)

    The Springfield 911 uses the same magazines as the Sig P238 and the Mag Guts spring and follower fit perfectly and have functioned flawlessly over 500 rounds thus far.

  17. Thomas C. (verified owner)

    So far I have no complaints, except that there is offering for the 40sw Sheild. Install is simple, works as advertised, good investment.

  18. Ramis A. (verified owner)

    I had a bit of struggle to install but it worked well, no hiccups at all

  19. Marc D. (verified owner)

    238 works great, The 8th round in the shield is really tight to load even with a speed loader, and it is very hard to rack in to the pistol with the slide closed. Its fine with the slide racked open. over all ii still like it because still have the extra round making 8 plus 1 with the small mag.

  20. Albert L. (verified owner)

    What more can I say. Works as advertised. Adds one more round. Feeds smoothly, well constructed.

  21. Aaron A. (verified owner)

    I bought p238 .380 7+1 and one 6+1 conversion kits to try on my Kimber Micro .380 pistol. I was a little bit skeptical it would work but when I installed the mag guys and went to the range worked flawlessly. Zero failure to feeds or jambs! The mags do seem to require a slight more force to load in but not a problem once their snapped in. Cool product and makes me feel a little more safer with 3 more rounds on me.

  22. stephen j. (verified owner)

    Received and installed the new spring kit, finally made it to the range. Ran 70 rounds through it with no problems. Use it for my carry magazine.

  23. David C. (verified owner)

    It’s easy to install just follow the directions on YouTube. So far so good its been perfect.

  24. Carlos (verified owner)

    Works, looks & feels precisely

  25. gerald (verified owner)

  26. Anonymous (verified owner)

    Second platform I’ve used these on, I’m a happy camper.

    My only tip is that these are harder to install due to the 1911 style magazines. Some of my mags didn’t accept an additional round, but reassembly fixed that. Go slowly, and keep the mag upside down like the instructions say!

  27. Steve B. (verified owner)


  28. SCOTT K. (verified owner)

    Really a sweet deal. I watched the video and read through the instructions. Only takes a couple of minutes and you have a seven round flush mount mag. I bought two kits and upgraded both of my EDC mags. Going to purchase a couple to convert my extended seven round mags to eight rounds for range practice. After installation the mags function exactly as they should.

    First assy could only get the same 6 in the magazine, took it apart and reassembled and got it right that time, now takes 7.
    I had the spring under the follower positioned wrong, thats the key thing everyone should watch for. Yet to fire it.

  32. Shawn B. (verified owner)

  33. Robert W. (verified owner)

  34. Ryan (verified owner)

    Easy to install and able to fit the extra round in magazine. The newer design looks much easier to install compared to original design.

  35. Steven Partridge (verified owner)

    Easy to convert, send to work fine, possibly a bit stiff but should soften up a bit with some use. I have not made it to the range yet, will definitely buy more if all goes well!

  36. Donald C. (verified owner)

    Works as advertised, adds that 7th round that would only be available with the annoying mag extension. Get one

  37. Jerry Lum (verified owner)

    Highly recommend, easy to install and no jams after 300 rounds.

  38. Donald (verified owner)

    Easy install and worked flawlessly.

  39. Ashton Faires (verified owner)

    Just received and installed, piece a cake. Seem to work, 7 round flush fit mags. Will test tomorrow. Have magguts in Glock 42, work great. Will by more in the future. A+ service! Thanks

  42. Daniel K. (verified owner)

  49. N. Bruce F. (verified owner)

  51. Jeff Ransford (verified owner)

    300 rounds no jams

  56. Eric (verified owner)

    I purchased 3 sets of these conversion kits for my Sig Sauer P238 HD to be used with factory magazines. They are built very well, and the installation was very straight forward. The included instructions are great, and I would recommend watching the installation videos available on the website as well. I saved the old springs just in case, but I don’t think I will ever need them. I know it only adds 1 round, but instead of a 6 +1 gun, now I have a 7+1. And for those who don’t like to have one in the chamber, you now have 7 in the magazine, instead of 6. Pricing is fair especially nowadays, shipping was smooth and fast. I’d highly recommend this kit to other Sig Sauer P238 owners. Good Job MagGuts.

  57. patrick lee (verified owner)

    No problem put it together, need to try at the range to judge.

  58. Jack W. (verified owner)

    I like your product. I have purchased three different kits and all work well. I plan to purchase two others very soon.

  59. Charles P. (verified owner)

      Your order was shipped promptly after the order was placed. Many packages are delayed as a result of recent bad weather across the country. It is out of our hands once we ship it.
      According to tracking it is out for delivery today.
      We hope you will contact us with an updated review related to the performance of the product rather than the performance of the Post Office.

  63. Travis Gillette (verified owner)

    The spring was REALLY tight at first! Wouldn’t fit 7 rounds. I had to take it back out and squeeze the flat spring for a little bit to get it to hold 7. Works good! Cycles good! Easy to install!

  64. David Christensen (verified owner)

    Putting the 7th round in is very tight but it does fit.

  65. Michael G. (verified owner)

    4 loads through them with no problems at all.

  66. greg casura (verified owner)

  67. Stephen M. (verified owner)

    Under-priced, exceptionally well engineered! Function flawlessly!

  68. Sal (verified owner)


  69. Karl (verified owner)

    Worked well once in, a little harder to install than the P365, but blame that on Sig making a bit of a PITA mag takedown procedure. Recommend if you carry a P238 frequently but a little pricey for just an extra round.

  70. Antonio (verified owner)

    Absolutely love them. I purchased these because my mag only holds 6rounds and I didn’t want the extended mag for printing reasons. These are great quality and fits the extra round perfect with a little space leftover. My P238 cycles perfect and shoots perfect. I have 4 mags and have these in all 4. The provided follower is better quality then the stock Sig Sauer follower, and looks cooler too. Hands down I will purchase these for every gun that I own as long as they make it.

  71. John B. (verified owner)

    Followed instructions , easy too install. Holds one more round!

  72. Theodore (verified owner)

    Works in a Springfield 911 flush mag for a Sig P238. Fired 50 rounds and cycled some more with snap caps without issue. Extra round is hard to insert at first but much easier after leaving the magazine fully loaded for a week. Only thing is be careful with the sharp corner on the follower when assembling, disassembling, cleaning, etc.

  73. Ramis A. (verified owner)

    Excellent, Price is perfect, I would love to have P365 at the same price 🙂
