Let me explain to you on your fingers what the potential danger of shortcuts in the hands of everyone is. First, a gun is one of the most technical types of weapons. In order to normally be able to handle a gun, you need to be long and turbulent, burning cartridges and money, training the processing of the descent, retention, stand. Without all this on the ground, all the bullets released in an emergency situation will go anywhere, but not in the attacker. And bullets from cutting weapons fly far, and to whom they will fly - a good question. Have you ever seen people training with now permitted rubber guns? At least 95% of owners, at best, once a year, burn a box or another of ammunition on the babakhing. Plus, you have to train the catch, the speed of guidance and that’s all. Secondly. The gun itself will not help. If the brains are few - it will only give confidence, which will aggravate the situation. Self-defense is not wearing a gun, but a whole complex of correct behavior, assessment of the situation, psychological stability in a stressful situation. You also need to be able to shoot. It is very difficult. Without all this, the gun owner in the best case will transfer the weapon for free use to third parties, in the worst - will get serious damage, in the worst - will break up with life.
In short, I think so, if you allow storage and wear - so only if you are a CMS for shooting. Otherwise, it will be a dangerous toy for you and those around you. // With respect, member of the FPSR/IPSC
