Yes, Vanguard is making them again but they are not being sold under the Un1Tec name. They are very nice (I have one). It is a two piece design with the back sliding overtop of the barrel and screwing into place. The barrel is all one diameter down the entire length giving you a very nice control bore.
Never argue with an Idiot. They will drag you down to their level and beat you with Experience!
It's not the WILL to WIN, but rather the WILL to PREPARE to WIN that will make the difference!
In-Hoc Signo Vinces!
