i have a sig 220, a 239 in 9mm and a 556 i think they are all awesome, im gonna place an order soon for the 1911 nitron with rail.
My primary CCW gun is my P220 carry - absolutely the sweetest shooting machine I've ever had the privilege of shooting. I absolutely love this gun!!
I, like a bunch on this list have a P220. Came a rat-hair away from selling it but quickly came to my right mind. NEVER again shall that thought cross.
