Some folks think it is too difficult to effectively conceal-carry
larger frame pistols like the 1911.

Here is an old training clip used my LEO's to learn about the
Filipino "Sparrow Hit Men". (Apprently, there are now Sparrow Hit
men in MS-13 and other large organized gangs).

Notice the 1911 is not visible at all (skinny guy advantage?) He is
using his off-hand to push the barrel up to expose the grip; his
presentation looks well practiced to be that quick. True long range
Kali.

Don't believe for one minute you opponent/attacker does not rehearse
how to take you out.

It is a battle of wills!

Train hard and train smart....
