After years of trying everything else, I've settled on VM2's for every day carry. I have 'em for the 1911, S&W 65, 66 and 686, and another on order for my G19.
Currently, the Glock 19 lives in a Crossbreed Supertuck. IMO, the Supertuck is every bit as comfortable and concealable as the VM2. I can wear it for extended periods of time with absolutely zero discomfort, same as the VM2.
To tell you the truth, every time I wear the Crossbreed/G19 combo, I find myself wondering if I really NEED another VM2.
Crossbreed makes a darn fine product.
