Introducing our latest addition to the MAG product line: the MAG19 EXT, the ultimate Glock 19 extended mag…
This upgraded-over-factory 20-round extended Glock 19 mag matches the Glock 19 & 49 perfectly, however, it literally fits ANYTHING that takes 15 round Glock-style magazine. 100% compatible with every magwell on any pistol that takes Glock 15 round mags. This includes: the PSA Dagger Compact, Ruger RXM, Fusion Firearms Compact Variant, Staccato, Derya DY9, Shadow Systems MR920, Polymer 80 options, and many more. THERE ARE NO KNOWN MAGWELLS THESE MAGAZINES WILL NOT FIT.
Styling wise, this product looks clean and matches the grip texture of most Glock pistols. The texture is slightly more pronounced to provide a perfect grip. We add the Scallop cut to the side for instinctual blind indexing when doing magazine changes. Unlike other extension kits on the market the MAG19 EXT uses our MTX 19 +5 that uses FIVE unique points of engagement to attach to the magazine body. This magazine will pass over a dozen consecutive fully loaded drop tests at 5′ to concrete. If you know XTech Tactical, you know we overbuild EVERYTHING we make, and true to our flagship MAG line up the MAG19 EXT is no different!
Just like with our other top-quality magazines for Glock, we listened to our client base and this magazine is upgraded over OEM options with:
- A stronger and longer-lasting, power 17-7 stainless steel spring vs OEM Glock music wire
- Our enhanced Delrin® No-Stick™ Proprietary Follower vs common nylon thermoplastics
- Our enhanced baseplate features unmatched durability, side scallops for extraction
- Side Scallop for ease of blind indexing
- Enhanced texture and front and rear tread for unmatched overall handling
Does NOT FIT 19x, if you own a 19x it has a 17 frame and you will need our MAG17ext 22rd magazine
THE ULTIMATE LIFETIME WARRANTY: These magazines are built to last… period. Our only exception is internet click bait for completely unrealistic tests. If you use our product like you would any workhorse magazine, we 100% will replace the magazine period. These are magazines you buy once and buy more if you want more. These are intended to be passed down to the next generation!

Very nice extended magazine. Thought it would be bulky, but it sits nice in the pistol.

Great mags so far. I’ve only shot 200-300 rounds through them so far, but no double feeds and nothing has fallen apart. I have recommended then to other.
JOSH HARENBERG (verified owner) –
These are the best aftermarket extended mags for Glock by far! I am looking forward to the release of their Glock 45 mags.
Connor Munn (verified owner) –
These are seriously the best mags I’ve used for Glock 19 platform. Specifically in my Dagger Compact they function flawlessly, never again will I use PMAGS for pistols, rifles only. OEM Glock mags or XTech only!
Now I just need them to make an extended Glock 17 compatible mag!
