Hypothetically, one and done. One and done for this reason: I was rocker for 7 years before I switched over to framing. Took months to adjust to my hammer in another location on my bags. I've bounced between holsters and caught myself reaching for something that wasn't there. I have not found a preferred mount. Out where I live I never have the thought "I could be armed". 7 miles away in the shithole city I have, more often than not thought "glad I am". A kid was just robbed of his week's pay while eating a piece of pizza in his car.
Like he now says. I was against guns but now, if the ______ would have shot me, at least I could have the option to shoot back. Yeah without a gun that would be impossible.
