It will work perfectly with my new suppressor! 8/11/2020 ** ** ** ** ** ** KyGunCo Verified Customer Matteson, IL Great 9MM , the feel, the fit, the style. One of the best 9MM hand guns I've shoot. 5/8/2020 ** ** ** ** ** ** James Puffer White Cloud, MI Outstanding firearm! I just added a Trijicon RMR and am now getting groups of under 1” at 25 feet. Phenomenal quality, balanced well and comes with all the mounting hardware. Highly recommended 4/29/2020 ** ** ** ** ** ** JUAN C TORRES GONZALEZ ORLANDO, FL This gun is the best bang for your money! Suppressor ready, optic ready, 2 24 rnd mags and a 17 round mag thats 65 rounds in a go. Nice carry bag!

This combined with great service definitely will make me a return customer. 4/28/2020 ** ** ** ** ** ** KyGunCo Verified Customer Salisbury, NC Very nice pistol out of the box for the price point. Set up for suppressor/brake and already has cut out for optic. Hard to beat for the money. 4/26/2020 ** ** ** ** ** ** Ray Smith Fife, WA Well to start, it’s an FN. Even if your not a one of their fanboys you still have to admit that they make some pretty solid guns.

Not to mention... who doesn’t like a 24 round freedom stick? 4/26/2020 ** ** ** ** ** ** Paul Dube Jacksonville , FL Flawless pistol. I fired 200 rounds of 115gr FMJ PPC blasting ammo to break it in. Not a single issue. Feeds, shoots and reloads. The balance and feel of this pistol is excellent and I am very happy with this purchase. FNH did a great job. 4/26/2020 ** ** ** ** ** ** Barry Smith Old Hickory, TN This gun is fully setup for any accessories you want to add. Has a high capacity of rounds and is made for action.
