It all depends on demand. Ruger routinely drops firearms from production that don't sell well enough to justify manufacturing space. In three or four decades they may have dropped everything but the Super Black hawk.Now that the American line of pistols are coming out will Ruger drop the SR line in a couple of years????
The SR series pistols aren't CA compliant either. The LC380 is only one left on the CA roster.you cant overlook that the rap isn't California compliant. That will probably keep the sr on the shelves for a while barring any changes to the new rap line. with aftermarket already in gear on the rap i think at some point they make a cali model and might drop the sr. who knows. based on reviews i wouldnt be surprised if ruger modified the back side of the rap to remove some of the fat butt that it has. would seem simple to modify or change the frame design to soften that issue without having to redesign the whole gun.
