Mine is kept almost exclusively for the most urgent of concealment needs - not often.
But - once you get the hang of ''manipulating'' for certain necessary operations it does have IMO a valuable place in carry options. I have some degree of ''spare real estate'' out front but high up - not the ''overhanging belt'' variety and like you can do a ''suck in of belly'' to ease access if needed.
Needless to say draw cannot be as fast as we might like but - that is trumped by at least having the piece there, on the person.
Charlie has I believe carried his 1911 full size all the years he has been making and selling these SmartCarry rigs. Just now and again I am real glad I have mine to fall back on when all else can't work.
