SSK-50 UPDATE
We are beyond excited to share this update with you from SSK Firearms regarding the SSK-50!
"I think we are finally at a point of confidence where we can comment on this. I have been hesitant to make any commitments for the last two years as I have learned a long time ago that until you have something sitting on the shelf, you better not make a promise. Currently, we have purchased the tooling and have contracted three separate casting companies to make the frame. Two seem to have the capability and we will have First Articles from one in a week and the other the first week of January. I anticipate production in February and shipments by the end of February. It has been a long, painful, and expensive process. We are committed to the project and resolve to do it right."
