Kinda backwards. How will they offer more calibers based on sales if some of the calibers wanted are not offered? They have the barrels, they have the LH actions. Combine them. Lol.
In my case, if they would have made a LH 450 right off, I would have bought one. But, instead, Ruger got the business. And, now if they come out with one, I won't be buying it.
