For what it's worth .................from a safety aspect a 1911 should never be holstered with a round in the chamber(cocked and locked). REASON: safety's can fail, or can be accidentally switched off with out knowing, while attempting to pull said gun from holster user may inadvertantly put finger on trigger and tug gun from holster hence shooting the wrong target. It doesn't take more than a second to rack a round into the chamber when and only when needed. A Sig on the other hand has a decocker and can be carried in a little safer condition (but that depends on the user) Also do rotate the round you chamber so the bullet doesn't get pushed into the case causing extreme pressures when fired.
Oh. My. God. You must be kidding me.
that's what makes America so great we all have our own opinions but don't say mine are crap' I didn't and wont say yours are crap. If someone is coming at you with a knife guess what, even if you have one in the chamber your stabbed. They did this test at my club with a long time action shooter who could draw pretty quick and he lost to the knife. But one stab doesn't kill a man but one bullet does.
Many of us have been carrying 1911s cocked-and-locked for many years without any mishap. My safety hasn't been wiped off inadvertently. In fact, at least one poster here who I respect a great deal routinely carried his 1911 in condition 0 (chamber full, hammer cocked, safety off). While a 1911 has a short, light trigger pull, so does a Glock, so by your logic, carrying a Glock with a round in the chamber is even more dangerous than carrying a 1911 with a round in the chamber. More importantly, the original poster is carrying a Sig 226, so cocked-and-locked is not an option for him.
If you ever need to draw your gun in a defensive situation, you need it real bad and you need
right now. While you can chamber a round quickly if you have two hands free, you may not have two hands free. Your support hand might be busy fending off the perp, pushing your spouse to safety, holding your child's hand, etc. There are techniques to chamber a round with one hand, but learning to do so quickly takes far, far more training than learning to safely draw with your finger off the trigger. There are significant disadvantages to carrying condition 3, and for someone to use their instructor credential to push condition 3 without discussing its disadvantages is unconscionable.
The "test" they did at your club was the Tueller drill. As for "one bullet" killing while one stab wound won't, that is more complete crap. Here in the US, 80% of people shot with a handgun survive. A shot or a stab wound might be fatal or survivable.
There are reasonable arguments for and against each condition of carry. You can post a reasonable discussion of the advantages and disadvantages. But for you to say that "from a safety aspect a 1911 should never be holstered with a round in the chamber(cocked and locked)" is just incredible. I have seldom heard such an ignorant statement about firearms.
