    Works great; +5 all day...but pricey

    Have 3 of these on OEM Glock Gen 4 mags, fit and finish is fantastic. Definitely pricey, and a pain to install. I get +5 all day long, if you are not getting the full +5 then ensure that the spring is not bound up in the mag (and also use an autoloader, the spring is nice and stiff). One of mine only held 18 until I disassembled it and fixed the bound spring. Now it's perfect like the others. I use these with my LC Carbine 10mm for 20 round capacity and it is way more comfortable than the big stick 30s - it looks fantastic with just the SLR extension being visible from the grip, but most importantly I can also shoot supported this way much easier because there's not a giant stick hanging so far down. No misfeeds or any other malfunctions. 10/10 fit, finish, and function. 6/10 price. Overall recommended if you can afford them...I need more but will probably wait for a sale, as they cost 3x as much as the magazines they attach to. Great product though.

    Works perfectly

    At first I could only fit +4 but after some use I was able to get +5 it just takes a little effort to get that last one in but it does go and it functions flawlessly. Awesome product.

    G20 mag ext

    In my g20 gen4 10mm putting +5 flared and slightly deformed the right angle edge of the plastic factory mag sleeve, the part that keeps the mag in the gun, after just 4 insertions. Thats the only edge at all that keeps the mag in the gun. Makes me believe w repeated use the mag will start to fall out as that edge gets rounded down. Not what we want to happen. 5 'will fit' but id say 'should not'. The tension is too great, the mag must be jammed in harder than normal to get it to seat so it puts a lot of pressure on that plastic squared edge, that isnt that deep either. I would not recommend +5, u need some give on the top round so it can depress slightly against inside metal parts (i dont know the proper term) when inserted, and +5 makes it rock hard. +4 is fine. Ill say it def should be called a plus 4, then id give 5 stars rather than 4. I will use it as a plus 4 for that reason unless the spring softens over time, then i will update this, but a good spring shouldnt for years. Also the hex screw isnt a standard size. Bigger than 2mm, smaller than 2.5mm. Bigger than 5/64, smaller than 3/32. So any size hex wrench isnt snug in the hole causing it to strip easily. I added a drop of threadlock just so i dont have to recheck the tightness, thatd be a great place for a lockwasher rather than a flat washer btw. The aluminum is light, high quality, strong, and the parts all fit great and snug. Im confident it wont pop off or break off if dropped. . The spring and follower are outstanding as well. Kinda unsure if im happy with it only because I really wanted a plus 5 not a plus 4. But it is certainly high quality, and the fitment is great, and snug, and that matters. And it does look cool as well.

    G20 gen 5

    Love it. Just wish I could get that last 20th round in. Have taken apart and put back together many times but still only holds 19.

    Glock 20 mag extension

    10/10 is all I have to say from the material quality to performance it’s honestly worth it, first time loading it up I could only get it to hold 19 but after a couple uses you should be fine

    Great quality +5 glock 20 mag extention

    This mag extension is hands down better than the others I've tried for the glock 20. I purchased 2. One worked perfectly held 20 right away. The 2nd I could only get 18 no matter how hard I tried. If you have had this issue take the mag back apart and make sure the sprig is seated flat on the bottom of the mag extention. Mine was curved where it caught sliding the extention on. I re-installed and works perfect with 20 rounds

    GLOCK 20 MAG EXTENSION 10MM

    A work of art. These are the real deal. The very best quality 10mm mag extensions. 20 rounds of the best millimeter. Custom spring and follower in the kit, included. Great invention!
