true, but shoulder rigs are somewhat impractical here in TX, since they require a coat and well its Texas and there is only like a month here you need a coat lol. ranges here won't allow shoulder holster rigs to be worn.
I don't think I will ever wear one. I haven't carried much, but I worked graveyard at a 24 hour firework stand and carried a Kimber 1911 in a holster inside my belt at the small of my back. Nobody knew except for one homeless drunk that stumbled out of the woods at 4 am one day and a leo that stopped by every night. It was comfortable and right about where my wallet would be when I pulled it out to hand it over. ;-)
