Of my three working shotguns, one is a fixed-barrel Winchester M97 and my Mouseburger 500 is not arranged for quick replacement, nor do I have a second barrel for it. My 870 is a Special Field model which isn't interchangable with the millions of *ordinary* 870s out there, so that's not a big consideration for me either.
On the other hand, the feature can be handy for maintenance, especially for cleaning the barrel of melted plastic from plastic wads, especially after 100 round-plus range sessions. I've still not worked up a semiauto shotgun in the configuration I want, with the features I want. My next attempt will likely be either a Saiga or a Mossburg semiauto, but we will see.
870 came with a 30” RemChoke. Great bird gun. Added an 18” RemChoke with iron sights. Works great with buck and a cylinder bore choke or slugs with a rifled choke (on a paper plate at 100 yds). If I could only have one, that might be it.
Hope yer good!
