There's another thread specifically on these pieces. Love the history, but maybe try to not hijack a thread.
I think most people who have bad intentions are cowards. As such, the open carry can act as a deterrent. I also think there is a place for concealed as well. Essentially, assume everyone is armed and we have much less likelihood of anyone using them other than to practice.
For me, the larger handgun fits my hand better and doesn't lend itself to cc as much as my wife's Walther. I will open carry on my own land and will after Sep 1 when new law goes into effect. I am not so much trying to say 'look at me' the Glock will be discretely carried, but not fully concealed, if that makes sense.
