The comments identified you as a first timer, so…
It seems you are reading far too much into everything. There is not an all inclusive training that lasts 20 or 40 hours each time we log on.
I use paddle holsters and have no problem with retention or drawing my firearm, I also have used should holsters, IWB, OWB, and cross draw, but I have been carrying both open and concealed for over 30 years.
There is nothing in the video that states you should only depend on your equipment, nor is there anything said by Machalowski that even suggests purchasing any item and simply ‘strapping it on’ and go out storming through the neighborhood without training and practice.
It was nothing more than a review. If you like the equipment and the review was helpful, do further research, and perhaps check it out in person, if it is for you, great, if not, great. If you do not like the equipment, great.
Just as with reviews of firearms, you may like some, you may dislike some.
Not sure what your point actually is, or what you are reading into the video. Have a great evening and Merry Christmas.
