Vandal, thanks for the feedback. There is a fine line between not enough grip rotation (which leave the grip printing) and too much grip rotation (which makes the slide print) as you have pointed out. Adjustable height was something I worked through quite thoughtfully, I have several iterations that have various height adjustment options. In the end, I was not happy with the execution on any of these and just went with a fixed height that for most people sat as low in the waist as possible (to aid in concealment), but also allowed for an unimpeded grip of the gun. We are trying to fix the ride height issue on our next iteration of the VELO. If it works, it will be a well done and well executed solution.
The point of the VELO along with all of Tenicor products is to be a purpose built product with a high level of performance. Most products strive for modularity, and I think the result is a significant compromise in performance. That's the reason I started making stuff in the first place.
With regard to the muzzle wedge, again we were pretty thoughtful about it and how to integrate it into the holster. I felt pretty strongly that the second angle was needed for most people that carry in the 1:00 to 1:30 range. The 10 degree rotation offered by other makers always seemed irrelevant to me when I tried to make those work. The muzzle wedge is intended to be right for most and not too much. My intent is that you can add more angle just by adding flat pieces of foam or neoprene. Personally, I'd just hit the junk store and get some kiddie foam alphabet blocks or cut up an old mouse pad. I'd also look at drilling a couple holes in the wedge and adding the cushion with screws instead of the conventional hook & loop. I plan on doing a DIY tutorial at some point.
The trigger bar wedge was originally a little bit less. I added some to it with feedback of SLG to make it work better for a G17/34. I think most will find it works pretty well, but I can see that one might find you get a tad bit too much rotation on a G19.
I have been playing around with the idea of a modular wedge system for a while and I know there are other manufacturers looking at that also. If you stop thinking about it like an add on foam thing there are all kinds of interesting ideas to execute a very well thought out product. The value of the thermoformed integrated wedge on the VELO is not just performance, but time and money too. It is all part of the forming process and the result helps keep the cost down to the end user. A set of 4 to 6 purpose built wedge are probably going to cost $30 to $40. How many people are really willing to add that much to the cost of the holster...?
