As long as I can remember I have used the Weaver stance. I used it even before I knew there was one. It just seemed the natural way to hold the gun to me.
Isosceles seems a bit awkward but maybe because I have become so used to the Weaver.
Isoceles and Weaver are good ... for two handed shooting.
Owniing both semi-autos and revolvers, there are differences that must be kept in mind.
Revolvers can be shot at odd angles of retention, without any finicky mechanics that sometimes crop up using sem-autos, depending on the caliber of choice.
The 1940’s USAR training film covers firing the 1911 one-handed.
The 1960’s FBI training film cover firing one-handed with a revolver.
IF, IF, all ‘you pistoleros’ out there, train with two-handed approaches all the time ... wha’ hoppen when yo’ don’ got but one hand tah use????? Wha’ hoppen if dah udder hand is dah one, huh? Kin yo’ do it?
Have always used the Weaver with a half camel toe tip.
There are two realities in gun fighting- practice and a lethal force encounter.
We practice presentation, tactics, marksmanship in varying manners so we can appreciate the fact that when the deal is for real and all the world becomes a blur of chaos, we have ingrained in our bodies and minds basic tasks and our training provides for a solution in a fast paced ever changing situation.
Bottom line- fight and move or die.
