Excellent FN509 Package for Pistol Optics

I’m extremely happy with my first optics ready pistol. There aren’t many options out there if you want cowitness height sights out of the box. These are the best 3 dot night sights I’ve ever used. The versatility of this handgun is what got me to choose it over others. I’m pleasantly surprised by the accuracy and recoil impulse. It feels great in my hand with all 3 mag sizes. Holosun 507C fits great. I suggest buying or borrowing a torque wrench to install optics. I tried to forgo one and was way undertorqued. The trigger is the week link. It feels horrible if you’re pulling slowly to the wall. It was hardly noticeable when shooting though. It’s got better with lots of dry fire practice using snap caps.
