New 1895's in Grade 1 (blued receiver) should be priced at about $1,100 or less (a 1895 from the 2002 catalog went for $1045 and it did not appear in the 2003 catalog) and that is the suggested retail price. I don't know too many gun shops that actually sell at suggested retail so I wouldn't think you're getting much of a deal here, even with the discount.
If it is a high grade (white receiver with engraved game scenes), then yes, you are, because a new one of those will run you somewhere between $1,500 to 1,600 at suggested retail.
I have an 1895 in 30.06. Yes it is a different caliber than what you are looking at but at least from my experience in 30.06, the gun itself is a pleasure to carry and shoot.
New manufacture 1895's do not have a crescent buttplate so that should not be a problem. Also, most people have trouble with crescent buttplates because they position them wrong on the shoulder. If you put it where the arm meets the shoulder (so that the crescent runs from the top of the arm down to the armpit), you will find that the crescent wraps this area perfectly and will not hurt you when you fire the gun. I have a .50 cal flintlock muzzleloader with such a buttplate and have never had an unpleasant experience with it.
