Comment / question:
My dealer has a P512HMKIII on order for me throught Davidson's. He told me they (Davidsons) are waiting on 155 of these pistols. Can you give me any idea when I might expect Ruger to ship these to Davidsons so my dealer can get one from them?
Thanks!
Response:
We will be shipping this model pistol to all of our distributors this month. We do ship on a regular basis. Depending on the orders Davidson's has and the order at which they fill them, will determine if your dealer receives one of the MKIII pistols.
