Adding the Shield Arms +5/4 Mag Extension takes a great platform to the next level. The Glock  series of pistols are known for their world class quality, ranging from excellent concealed carry guns to some of the best competition handguns on the market today. With that said, many of us are always looking for a way to squeeze out a little more performance from these already great pistols. One way we can try to do so is by adding some extra ammo capacity to magazines that we already own. 

If you want to add some capacity to your Glock, these magazine extensions by Shield Arms will more than doo the trick. These are well made magazine extensions that are made in the USA, have a lifetime manufacturer warranty, and install relatively easily. Taking an existing magazine and removing the floorplate and spring, you’ll simply replace it with the Shield Arms Glock 17/22 +5/4 Mag Extension, which includes springs. The rugged aluminum design will last years, and the slightly more powerful than stock spring should assure you that your Glock will continue to feed well.  

These are meant to work with the OEM Glock magazines. Also, these should work just fine with any flared magazine well that also accept the standard magazines from Glock. Of course, make sure that any modifications you do to magazines are in line with any local and state laws.  The Shield Arms Glock 17/22 +5/4 Mag Extension  are a relatively affordable way to add extra capacity to your Glock Pistols
