Last summer I met some outfitters in Ennis, MT. To a man they carried Glock 10mms for their sidearms. I have a Kimber Eclipse 10mm. Still working the bugs out but like the platform. Like others have said here, I doubt Ruger will offer a 10 unless a distributor asks for one on the SR1911 platform. Remember how long it took Ruger to chamber a Blackhawk in 44 Special?
