I think we reached the saturation point on guns a long time ago.
Guns are a unique commodity, as far as commercial sales go. They rarely wear out, and innovation is at best marginal, so gunmakers can't use "planned obsolescence" to spur sales. Gun collectors are mostly involved in the secondary market, so manufacturers can't really sell many guns to collectors.
The one thing that has promoted gun sales, in recent years, is panic induced by periodic efforts to ban or restrict them. Truly, Obama has the title of "the world's best gun salesman." But at some point, the public is going to get wise to the panic-induced ups and downs of the gun market, and refuse to play that game. Besides that, the last panic, I think, resulted in just about anyone that ever wanted a gun (the last holdouts) getting one.
We're going to be in a situation where supply outstrips demand, for quite a while. This is not a good time to be a gunmaker.
