For sometime I have carried the DeJammer. Actually I began carrying it on a whim by including it on a big order from Ayoob's Police Bookshelf. Since I always saw Mas with one and decided that since almost every product he had recommended worked for me it was worth the few $$$ to try it.
I took to it immediately from all of the non-Kubotan reasons. Primarily because it put my key in my hand faster than from my pocket. Also, I have mostly carried revolvers for the five years I have carried concealed and a malfunction with a revolver that would required the DeJammer could not be cleared otherwise in a firefight. Although I agree and practice the "second gun transition" practice it is sometimes impossible to practice being extemely warm natured and living in the Texas summers. Sometimes a Smith & Wesson Centennial is as good as it gets.
Although I have not taken a Kubotan class, I have gone through two of the manuals. The class is on my tado list once my wife and I buy a house.
Overall, the product is worth the money and then some. I carry mind on my weak side shoved into my pants between the pants and the underwear.
Try it. The worst that can happen is that you spend a few dollars and end up giving it to someone who can use it.
Call Police Bookshelf to order at 800-624-9049.
Good luck and good shooting.
