Most Helpful Positive Review I recommend!
I definitely recommend this magazine extension, easy to carry concealed and holds substantially more ammo and the color looks great!
Most Helpful Negative Review COMPLETE WASTE OF MONEY
I just received these today and am a first time buyer of ***, and of second time purchaser of Tyrant products. I will say this is the LAST time I will buy a Tyrant product and potentially the first and only time I purchase from *** as well due to absolutely how HORRIBLE these extensions turned out t...

Works with Magpul xmacro mags

by Rick, Verified Owner from CA, United States Written on May 22, 2026
This product is awesome. It’s a little rough to put in at first, but once it’s in, it’s working flawlessly. It also works great with the radiant backstrap and Magwell.
Pros:
  • None
Cons:
  • None

Another win for Tyrant.

by hughy, Verified Owner from OH, United States Written on January 20, 2026
First of all. Dont be an idiot. No this does not work with any other 365 mag. You have to have the 17rnd. Plenty of folks on here dont do thier research. Tyrant is top notch for mods, always love thier products. Tolerances are supposed to be tight.

Clean look and Easy install

by Patrick Brady, Verified Owner from NC, United States Written on December 31, 2025
I’ve been a fan of Tyrant products for a while now. With these +2 mag extensions I can carry 19 +1 x2 magazines giving me plenty of rounds for EDC. The mag extensions aren’t so long that they imprint very much at all and they look great too. The install is extremely easy and takes just a few minutes. I’ve run about 250 rounds through them with zero malfunctions so far. All in all great products 10/10 �
Pros:
  • Price
  • Quality
  • Looks great
  • EASY INSTALL
Cons:
  • None
Best Used for:
  • EDC
  • Range Time
  • increase capacity

Easy Install and not too flashy, I would give it 5 stars if it fit flush to the Maxwell

by Jonny Blaze, Verified Owner from TX, United States Written on August 13, 2025
From the two mag extensions I purchased this one was easier to install, but it does not fit flush when the mag is seated into the P365X Macro. There is about a quarter inch gap. Possibly if I get a flared Maxwell it may cover up the gap, but I have another Mag Extender from a different brand that fits flush without a Maxwell. So keep that in mind when purchasing this one.
Pros:
  • EASY INSTALL
Cons:
  • Doesn't fit flush
Would recommend: Yes

Spring issues

by Derek B, Verified Owner from AL, United States Written on June 19, 2025
The quality of the mag extension itself is pretty great, but the spring not so much. I’m not sure if I received 2 defective springs or they weren’t designed to have enough force to hold the slide open after firing the last round. Based on the reviews it looks like it’s either hit or miss. Either way I would say proceed at your own risk.
Would recommend: No

Good BUT………

by MrDrProfRay, Verified Owner from NV, United States Written on March 4, 2025
Couldn’t decide between 4 or 5 start but since it does what it was intended for I let it slide, BUT the only thing is the spring is a tad bit short where it won’t slide lock after the last round. Had them for a lil over 3 months but no problems here
