I picked up a Bulldog case from Questar. Actually, I got two, one for my 14 inch norinclone and one for the R22. I believe Mark has a 35 inch and a 44 inch in stock. The HP9-1 wouldn't have fit into the shorter case so I got the larger model.
I suspect when the Spec-Ops stocks come in, the gun will fit in the smaller case.
For the money, i think they are well worth it.
