If I had to pick it would be either an hk (with lem) or glock with gadget ect.. something that had positve feedback whether or not the trigger was being pulled and the ability on my part to easily overpower it ie. my thumb on top the hammer or gadget. As Doc put it though as long as you use very prudent methods for reholstering it can be very safe, I just prefer to have a little extra safety.
eta: if I was to reccomend a 1911 I would definately prefer a series 80 . Also as I believe Doc has recomended before I would want the 1911 set up properly there is very little inbetween on 1911's if you can't afford to spend a fair amount of money on a good one, don't waste your time.
