Description
The Tapco TAP22099 is a no-frills magazine extension that gives your Glock 17 or Glock 19 an extra 5 rounds of capacity. It's the kind of upgrade that matters when you want to spend more time shooting and less time reloading.
These extensions are straightforward to install and work with standard factory Glock magazines. The black finish matches stock Glock parts and blends in with most common setups. Tapco has built a reputation over decades in the aftermarket parts space by focusing on durability and function without charging premium prices.
Whether you're hitting the range, running competition, or training, more ammunition on tap means fewer interruptions between strings. The extension adds weight to the magazine base, which can also help with reliable mag drops during reloads if you're using it in a setup with proper magwells.
This accessory is designed for use in environments where magazine capacity restrictions don't apply. A +5 extension on a G17 or G19 is a common setup across training facilities and matches with USPSA competition standards.

Frequently Asked Questions
Will the Tapco +5 extension work on my Glock 19 magazines?
Yes, the TAP22099 is designed specifically for Glock 17 and 19 factory magazines. Make sure you're using standard OEM Glock magazines for best results, as compatibility with some aftermarket magazines can vary.
How difficult is it to install this magazine extension?
Installation is straightforward and typically requires no tools or just a basic punch. You'll strip the magazine down to the baseplate and follower, insert the extension body, add the extended spring and follower, then reassemble. Most people finish in under a minute per magazine once they've done it once.
Can I use this extension with older Glock generations?
The TAP22099 is compatible with Glock 17 and 19 magazines across different generations, though you should verify compatibility with your specific magazine generation before purchase. Feed lip design and follower shape can vary slightly between older and newer Glock magazines.
Will loaded magazines with this extension fit in my magazine pouches?
The extension adds height to the magazine, so fully loaded mags may be tighter in some pouches or holsters. You might need to size up your mag carrier or purchase extensions designed to work with your existing setup.
Is this legal for competition shooting?
Magazine capacity rules vary by competition organization and location. Before using this extension in any organized event, check the rules of the specific competition or range where you plan to shoot.
