Another option would be to either cut the barrel down and make it a carbine (probably not what you want to do with a nice Hawken), or you could order a Green Mountain drop-in replacement barrel and have it cut down to carbine length.

It's too bad T/C doesn't make the White Mountain Carbine anymore. I have one in .50cal that used to be my dads, and it is one light handly little rifle. Granted, it's not a super-duper, 150 grain fire-breathing monster, but stuff a 385 grain Great Plains conical down the pipe and it'll flatten deer out to 100-125 yards pretty well. Kicks like a mule, though, because it weighs only about 6 pounds with a light 4x scope. Without a scope (which are illegal in CO for ML season, anyway), it'd weigh no more than 5.5lbs.

If I can dig out my digital camera I'll post a picture of it. It's a great little gun.
