I have an opportunity to buy Dan Wesson model 15 357 with a 4 inch barrel, wood grip and adjustable rear sight for about $500. Condition seems to be very good to excellent. I've heard some stories, that Dan Wesson are one of the finest and most accurate guns. But since this is not a production gun, I can not read it's specs from the web site... Can someone please tell me if the size and weight of this model closer to S&W L-frame or K-frame? Also how this gun compares to S&W Model 19. And finally, is the asking price fair for (lets say) an average condition? Thanks.
