A buddy bought a 20 ga, 870 express and lost the barrel. He bought a barrel for it, but not being a very savvy gun guy, he got a "large ring" 20 ga barrel for the old 20's built on the 12 ga frame. He decided the gun was just going to frustrate him so he gave it to me. I picked up an 18" barrel from Midway USA and now have a light weight 2 ga riot gun. Should serve the wife well. Total investment $149. I am awaiting Choate's web site to get upgraded so I can order a +2 mag tube extension. I will add a side saddle to round it out. Handy little gun. Now I just need to buy a couple of cases of 20 ga ammo. I have been collecting a few odd rounds of 20 ga and have nearly 100 Winchester AA hulls. I guess I need to invest in a Lee shotshell loader too.
