Thoughts on 11 O'Clock Cross-Draw Carry...
Just my unprofessional opinion, but I like it.
Yeah, it has a few draw-backs, but so does every other means of carrying a gun.
More susceptible to snatching by someone in front of you... Maybe. But a gun carried in the 1 to 6 o'clock position is pretty easy for someone behind or beside you to snatch too. And although I try to never let anybody get up too close behind me, I find it much easier to keep them off of my front side.
After all, if they're in front of me, they're right there where I'm looking. They do anything silly, and I'm much more likely to have enough warning to actually do something about it... like step back with my right foot while jamming my left hand into their face and drawing my gun with my right hand. If they're behind me, like in the line at the grocery store or bank, then I either have to keep looking back ( which can draw a lot of unwanted attention ), or wait 'til I feel a hand on me. ( Which will probably be way past "too late" )
Seated in a car... yes, it's tough to get your gun pointed at the passenger side in a hurry with your right hand. But with the gun holstered at 10-11 o'clock, you can reach it with your left hand too. And it's usually easier to move your left elbow back while in the driver's seat than it is your right, especially if you're trying to turn toward a threat. You still have to remember to draw left handed though.
Sweeping the crowd/your own arm... learn to draw the gun in such a way that the muzzle stays pointed downward until it needs to roll up to the target. You can generally slide your hand and arm around your body and line up with the target pretty quickly, while keeping the gun pointed in a fairly safe direction, even in pretty tight quarters. From there, it's either fire from retention, or raise the gun to eye level first.
Anyway, that's my thinking on carrying cross draw.
