Many thanks for the endorsements. One of the 21s I am interested in is a deluxe field model for $3495. The gun has nice wood with the kidney pattern and a Simmons after fitted ventilated rib. I remember reading that Simmons installed a lot ventilated ribs on Mode112s and 42s. I presume they also did 21s. My question: is the after fitted rib cause the price to be what it is?
