Bad idea. If you should happen to fall it puts a solid lump of metal right in pressure alignment with your spine. Crushed disc or worse? Also, think about this: There is an extreme risk that in the midst of your draw you will sweep your own body with the muzzle creating a critically dangerous situation under the pressures of a combat situation. You might just accidentally shoot yourself. How embarrassing! Maybe the bad guy will laugh himself to death before you bleed out.
I’m planning on a much small carry piece soon that I hope will be easier to carry.
