Looks and works great

i purchased six of these around 2009 or 2010. i have used two of them and they have functioned without flaw (no jams, failure to feed or problem loading 30 rounds) for seven years pushing hundreds of rounds through both. unless you look very close you can't tell much difference between the texture of the grip of the Five-seven N and the magazine. i would recommend this product to anyone.

Bought and tested 3 of these mags

I tested 3 of these 30RND 5.7 PRO MAGS I purchased from Brownells in both of my new FN Five-seven pistols with about 60 previous shot rounds in each of my two pistols. At about 100 RNDS.. 2 mags jammed..one 20RND Factory Mag.. once, and one 30RND mag once. Next range trip I shot over 400RNDS in each pistol alternating both 20RND Factory mags and 30 RND PRO MAGS..FLAWLESS results. My next trip to the range I tested more than 200RNDS in each pistol using mostly the 30RND PRO MAGS... again... performed perfectly. Ammo majority using 197Sporting rounds, plus two boxes of 195, and 12RNDS of protector Elite ammo.

Awesome product!

I love high capacity mags that work! And this is one. It adds 10 rounds to the factory 20 round clip. The extension only hangs out of the pistol handle two inches. The fit and finish looks like a factory made piece. The mags will even fit in the original FNH five-seven hard case with a couple easy cuts. And looks factory. I can't say enough about these extensions. Buy them, three off them. You won't be disappointed. And boy do they grab the attention of others.
