Nice, thanks for posting the article! I was having trouble finding a copy.
So from the article, it sounds like 24" is the one to get, but 26 or 28 will be fine, especially if you go with a 12-round tube since it'll extend past anyway?
The article mentions that with the tube it was 11+1, but it looks like the magazine tube is flush with the 26" barrel - how did you manage that? It seems like others are only able to get 10+1 and have it flush.
