The 28 and 12 guages sell best, and double triggers are harder to find, but they all seem to sell well. Considering the quality and that they were around $2800 new 20 years ago, they have increased in price surprisingly little. In other words, they may be bargains still, even at $4-6000! And they are wonderfully built, beautiful little guns (I've had 6, and a little 28 ga is now my favorite grouse gun).
