I have seen claims that the C9 shares a lot of parts with the 995TS. Does anyone know if it is possible to mount a carbine length barrel on a handgun? Has anyone tried this, do the parts fit, and does the gun function safely and reliably? Please be kind, I have a legitimate and reasonable application (forced on me by less legitimate and less than reasonable local gun control laws where I live). Thanks in advance for any constructive input!
