There are a few tactical looking offerings.. but..
You took bears with a 1911 .45 while on the job? That's one heck of a story I'm sure! I shot a few watermelons and baby coconuts. LOL. That's my 9mm (carbine) story.
The carbine equivalent to your 1911 I can think of is the Kriss Vector in .45ACP. That's pushing the price range I shop in already so I don't dare look beyond.
