great product, FN had...
great product, FN had a rebate for extended mags and when I tried to claim the rebate they said they couldn't fulfill it so I was left empty handed, gun is a little heavy and a little wide if your looking for something slim and lightweight but for me it's a solid feeling conceal carry handgun.
