Naming this gun the Model 21 o/u is a marketing move by CSM and I understand that, but it is going to cause confusion down the road. It certainly won't have the impact of John Olin's sxs, but it will, at some point, have to be explained when they are brought up in conversation.

"What's that guy shooting down there?"

"Oh, he's shooting a Model 21."

"Nice, I like those sxs's."

"Oh, it's not a sxs, it's an o/u."

"Huh, I never knew Winchester made an o/u AND a sxs called the Model 21."

"Oh, they didn't, this gun is made by Connecticut Shotgun."

"Who?"
