Until you shoot yourself in the johnson.
That's a high price to be cool if you ask me. Be safe, not cool.
To be cool?
I don't carry a gun to be cool. I carry a gun because it's a tool to protect myself and my family.
I don't carry Appendix to be cool. I carry appendix because I can draw faster. Because I can access my gun with either hand. Because I can better protect my gun in this position against the bad guy.
I carry appendix in a proper quality expensive holster. I train with my gun. I have trained to carry my gun appendix.
I have no worries on shooting my Johnson.
