That is a great deal. I got my 41 mag silhouette at cost last year and it was $1250.
The barrel length is only a problem if you intend to carry it in a holster and draw it when you see game. I hunt with mine in my hand, hammer down. Then all I have to do is cock and fire. It works great for brush hunting and is 1000 times easier to carry than a scoped rifle.
I would say buy it and try it out for a while. You can always rebarrel it or cut it down later.
Heck you might even shoot a silhouette match or two, it is an excellent tool for that.
I love mine, I think you would too.
