according to everything ive read, carrying with the hammer down (on a 1911 anyway) on a loaded chamber is responsible for more accidental discharges than all other methods combined. it took a little getting used to, especially by my wife and mom who both know i carry but both dropped their jaws the first time they saw the hammer was cocked. even though the thumb strap goes between the hammer and firing pin, i guess it does look scary.
what make is that? ive owned many 1911s but never an original like that. the fact that it functions so well now is proof of a superior design.
heh.....sounds like a fine idea.
