Based on my experience with the design and the input of others who's opinions I lend a lot of weight to I feel the design is unsafe. Under stress shooters tend to push down before pulling up. Any mix up in timing can cause an ND. Your welcome to train in your concealed holster. It is a good way to build reps and determine if the holster you selected is good kit. I also recommend that anyone who's serious about pursuing firearms training pick up the following 3 items: A real Gun Belt, a Kydex OWB Holster (I like Bladetech and its available in the shop at Interstate Guns in Hammond), and a Kydex Double Mag Pouch. Buy quality stuff and it will out live you.
