In what actually plausible circumstance would you be unable to draw and cycle the action but still be able to draw the weapon unhindered? My point being that any physical confrontation with someone who is so close to you as to preclude engaging with a gun from Condition 3 (loaded magazine in weapon, no round in chamber) is close enough to interrupt your doing so with a gun in Condition 1 as well. Ask any firearms-rated CQB qualified instructor, don’t just take my Krav Maga-novice word for it. I won’t clog up your comments with YouTube links, but search “krav maga gun defense” there and see for yourself.
Just for the record, I prefer to concealed carry my Colt Commander in Condition 3, primarily because I’ve taken the trouble to learn how to take your gun away from you from 5-7 yards initial distance and am painfully aware just how susceptible I – anyone really – am to the same maneuver under the same conditions. The remedy to this threat is to maintain a heightened sense of situational awareness and be willing to act upon it pre-emptively. This means noting something “wrong” about your surroundings and maneuvering to a defensive position as you exit the area. Drag your companion by the hand if necessary; shop elsewhere or later if necessary.
If any of us are ever compelled into a defensive shooting, it will be as a result of either a deliberate, intentional attack from cover (the classic “ambush”) – and I include home invasion in this category – or a failure to exit the area upon notice of the onset of an armed attack in your immediate vicinity (there are justifications for this last, but the basic mindset must be one of “personal defense” rather than “proactive defense”). The former situation is time for “coffee-do” or some other form of hand-to-hand combat and the later permits sufficient time to cycle your weapon into Condition “0″ as you seek out cover from which to defend yourself.
You’ve practiced carrying in Condition 1 (and, yes, I do practice first shot placement from Condition 3) so you should continue as you’ve trained to do, but give some informed consideration to expanding your personal defense options as well. I can’t fully express how much less psychological burden I experience because I don’t have to rely on my gun to violently defend myself.
His (and others) points regarding potential gun sub-system failures (like redundant "safety" mechanisms) all strike me as obfuscation of the primary thesis; is it better to train yourself to operate your gun or let your training be dictated by the gun's optional conditions? I train to carry (and if necessary, fire) my gun from what I regard as the most all-around safest condition of general (that is, concealed under one or more layers of clothing or within a container of some description) carry, Condition 3. I arrive at this decision in large part due to my also training in Krav Maga - specifically, training to engage with or against a firearm. In my opinion, while these tertiary concerns regarding potential weapon mechanical failure are valid, they would be better addressed in a gun maintenance class (or by a hired professional smith) then as part of some carry condition justification.
