I am having trouble finding a Blackhawk Serpa holster for my new Model 34. I have one that I use with my 26 and I'd like a similar rig for the 34. Does anyone know if a rig made for the 17 will work? I realize that the barrel may go past the end of the holster about 3/4" but I can work with that if otherwise it works. Thanks in advance for your help.
