I guess that would depend on your definition of "decent". Most of the ones I can think of are semi auto replicas of SMGs.
I've had a semi auto Tommygun for many years now. Mine had been reliable and very accurate, but few would describe it as a "decent" rifle. It's expensive, awkward (ergonomics) and heavy as hell. like 12lbs heavy and a drum mag only adds to it.
The Marlin Camp Carbine always seemed like a decent little rifle to me, although I never personally owned one. Its been discontinued for some time, and good luck finding one. Also, if you do, you'll find it (most likely) waaay overpriced (in my opinion) but its a seller's market...
If you're looking for a light, handy, rifle or carbine in the traditional sporter style for a decent price, there is none I know of in current production.
Simply put, while the .45acp does get a performance boost from a carbine length barrel, its not as much of a useful increase as some people think it ought to be, compared to some other rounds, such as .357 & .44 magnum.
The 9mm guys don't want a .45 (of course), the semi auto bullets usually used are not optimized for small game, and .45acp even out of a carbine isn't powerful enough to be well regarded for larger game, either.
My Tommygun will put 5 shots in one ragged hole at 25yds, and I can ring the 200yds gong on the range using the ladder sight. DO I carry it in the field? No. its simply too heavy and too awkward for that, since I have smaller, lighter guns with equal or more power and range to choose from.
On the other hand, there's nothing else quite like it, its a childhood dream fulfilled, and it is fun, IF you can hold it up!
Good Luck in your search, there might be something out that that fills your bill, but I don't know of any, sorry.
I chose this because it has
style!
But practical? no, not really.
