I had a guy come up to me a couple years back and start running off at the mouth about his Gold Cup and how at his elitist gun club nobody would carry a 1911 condition one, blah blah blah (the guy really just would not shut up). I was ever polite, but I was sorely tempted to tell him to mind his own business. Instead, I explained that, as surely a 1911 owner like him would know, the thumb safety is extremely effective and secure at blocking movement of the sear, and it fact non-series 80 1911s are actually more likely to fire when dropped with the hammer down, etc etc etc. All to no avail.
I switched to a leather thumb-break style holster (from my SERPA, which broke) a little over a year ago. Since then, I haven't had any remarks about the state of my hammer. Which is just as well... what a boring conversation. (yawn)
