Does anyone know of a 28 gauge single shot that can be purchased in the USofA that has screw in chokes? Found the perfect one, but only can find it in Canada (Federation SB28 28g 3" 20" Synthetic). Not worried about WHAT choke it takes, because I can run up to Trulock in person and get them to fit it with the right one. I do not intend to use it this year, so no big rush. Took me about 5 years to find a double trigger O/U in 20, but I finally got one and set it up and killed a bird with it this year. Still need to kill one with a 410 though.
