Here's a short update. I've worn the Supertuck a few more days, and it seems to be taking shape nicely.
The retention at the front of the trigger guard seemed a little excessive, so I heated it up with my heat gun and reduced it some. It now slides in and out very smoothly, yet isn't going to come out unless I want it to.
I also added one notch worth of forward cant. I do like the option of easily adjusting the ride height and cant to suit my preferences.
While walking around a quiet department store a few nights ago, I did notice that it's not exactly a silent holster. It's unlikely that a typical person would notice it, and I doubt that they'd have any idea what was causing it.
I wore my VM2 a couple days ago to compare the two, and in the comfort department, the Supertuck wins hands down. The VM2 is quieter, just as easily concealed, gentler on the firearm, and much more finely crafted.
I think my future Rock will be very happy riding in the Crossbreed, while my CCO is used primarily in the Milt Sparks.
Overall I'm very happy with the Supertuck,and the comfort more than makes up for the few weaknesses.
One of my cats must be ready for me to load up some ammo....she's tearing up the shipping box the Speer Gold Dots arrived in.
