Scherer Glock 27 magazine extension review

As a license holder for concealed handgun carry, one of the most important aspects of carrying in public is to keep my weapons, well, concealed. This is primarily accomplished thanks to the small size of the handguns I carry, and partly due to my programmer-ruffian style of dress. Having a smaller-frame gun can solve one problem, but may lead to others. The grip on my Glock 27 is not long enough for all four fingers to fit around. My pinky dangles off the bottom, which not only feels disconcerting, but amplifies my naughty marksmanship habit of shooting low and to the left.

Two companies, Scherer and Pearce, manufacture magazine extensions for my 27. A mag extender replaces the “foot” of a factory magazine and in some cases allows for increased cartridge capacity. I selected the Scherer +1 magazine extensions, primarily because I liked the checkering (texture) on the extension, and also because they were $3 cheaper apiece than the Pearce. If I didn’t like how the extenders felt or shot on my Glock, off they’d go.

I purchased my extensions and a Glock armorer’s tool from They processed my order promptly, and I was pleased with my shopping experience. I’d definitely recommend them again.

This is my 27 with a factory magazine inserted. I have the Scherer and a penny for reference.

Here’s the magazine with the Scherer extender. You can definitely see a difference in the length of the grip with the magazine extender.

The Scherer makes a huge difference in the length of the grip, and my comfort.

I haven’t had a chance to take my gun out to the range yet, but I am anticipating a difference in recoil control and overall accuracy.

As an added bonus, we have a game!

DrFaulken is packing heat in two out of three of these pictures. Can you pick them out? Mouse over once you’ve decided. The guns will reveal themselves.

So far, I couldn’t be happier with the mag extenders. It was a low cost solution to address one of my biggest gripes about my daily carry gun. $5.95 each is definitely cheaper than several hundred on a new heater. Scherer magazine extenders are available at, and other gun retailers.

    Anything less than 16 rounds FTL :p Glad you like those extenders, I’d wager they really help with controlled shooting.

  2. DigitalChris says:

    Real men just have their pinky removed.

    I really enjoyed that mouseover to make you strip down. I think you may be onto something there.

    I have just acquired sherer extenders for my Glock 26, but I can’t for the life of me figure out how to get the old base plate off. In addition to the obvious post through the base that would have to be pushed up out of the way, the flat base has two “ears” on either side that prevent the base plate from being pushed off, once the post is out of the way.

    Any suggestions?

    Hello Jim, welcome to Gibberish!

    Have you tried the process outlined in these instructions? I had to pry pretty hard w/ my Glock tool, and some of the plastic was distressed because of it.

  5. JOE says:

    Push the post up through the base at least 1-1/2″ using a small screwdriver or allen wrench. Then use a small clamp (I used a C-clamp) to compress the sides until the base slides right off.

    Love my 27 and my Scherer extensions. I carry mine in the small of my back and on my angle daily and have never had an issue of concealment.

  7. Jimmy says:

    I just purchased the same gun and decided to pick up the Scherer extensions after reading your blog. They came in two pack. I just installed them and the gun fits much more snug now. I haven’t done any shooting yet but I’m sure I’ll enjoy them.

  8. bdadles says:

    When the extender is added to the magazine does the spring still have enough pressure to allow the magazine to empty properly or does the spring need to be changed also.

  9. drfaulken says:

    Hello bdadles, the stock spring has enough pressure to feed properly. In fact — it’s embarrassing to admit, but the springs in the mags are going to be thirteen years old in August and they still do the job.

    Great article! I have a 27 and am looking at purchasing the mag extenders. What kind of holster are you using? I see you have a mag holster as well. Are you happy with your concealed carry comfort, etc? Any suggestions on where to purchase the appropriate holsters?

  11. drfaulken says:

    Hi Pete, thanks for your comment. I was probably wearing my Galco Yacqui slide in those photos, but I can’t remember.

    I stopped carrying the G27 after almost ten years in favor of the Rock Island Armory Compact Officer’s model 1911 for the last six months, and/or my Kel-Tec PF-9.

  12. Bones says:

    This is just my 2 cents, but I don’t like the mag extensions on my Glock 27. Now I have shot my Glock 27 with and without the extensions. I do have fairly big hands, so my pinky does hang off of the bottom, but I shoot my Glock 27 without the grip extension better than my duty weapon, which is a full-sized Glock 22. During my last qualification I hit the target 56 out of my 60 times with my Glock 22 and hit 60 out of 60 times with my glock 27. I also know quite a few people that shoot their baby glocks without the mag extensions, it just takes a little getting used to. So, in my opinion if you plan on buying a Glock 27 and the mag extensions you are better off just getting a Glock 23 because it has the same length grip and a slightly longer barrel. Like I said that’s just my 2 cents and if you got a Glock 27 with the extensions and it works for you, that’s cool, I just like my Glock without them.

  13. Shane says:

    I was taught to point my pointer finger foreword and use my middle finger as my trigger finger. This leaves only the ring finger and pinky to grasp the smaller grips on the 27. Hate it…love it…like it…or leave it!?
    I love it!! It gives so much more control and only takes a little getting used to.
