Salient is making the nicest Glocks in existence. However, even having "nice" and "Glock" in the same sentence makes me cringe a bit. I beat the shit out of my Glocks, and love the fact that I can do that without worrying about them. If you have lots of disposable income, then you'll have a hard time finding a better Glock.
Honestly though, you can get 90% of that gun for 1/6th the cost, especially if you are fairly handy. The only thing that you'll have a hard time doing is the titanium nitride/fluting of the barrel and the weight-saving cuts on the slide. You can get some custom cut slides from Lonewolf though.
My take is that these are phenomenal if impractical guns. I'd love nothing more than for someone to give one to me. For the price people are asking on Gunbroker, I could build three STELLAR custom Glocks for one Salient.
