I have posted on this before--It is a mystery to me why manufacturers can't give away these semi-auto caliber revolvers when they are in production. Then once production stops, the same, $200-$400 revolvers become highly sought after, $2000 grail guns.
Correspondingly the biggest mystery to me in modern firearms marketing/production is why there are not readily available revolvers in 2.5, 4 and 6 inch in 9mm, 40 S&W, 45 ACP, and maybe 10mm. It would seem they would be ideal companion pieces to the pistols. Further, one could take advantage of mass-produced, relatively cheaper bulk ammo the common pistol calibers seem to generate. (Of, course 10mm is an exception to that).
When I have mentioned this before the highly knowledgeable forum member here have told me "they don't sell." Yet I see thread after thread, post after post, both extoling the virtues of 9mm/40/45/10mm revolvers and searching for them. And when they do come up for sale on here, they are gone instantly.
