I just picked up a companion piece to my for-home-defense 870. A used 870 express w/26" vent-ribbed barrel, also in 12 gauge. In the same rack was a used Wingmaster - a little older, but very pretty with a glossy blued finish and glossy furniture, too, but she had a fixed full-choke barrel, so I opted for the express with the removable choke insert.
The clays and doves probably have nothing to fear just yet, but I'll be doin' my homework!
Now I need to get a swivel set installed for a sling. Anything I need that I haven't thought of?
