Re: weaver or isoseles??? and why
Just to reinforce a point already made....
In my job we train on a principle worded such as "Terrain dictates technique". This principle applies to a lot of stuff and includes shooting positions with carbine and sidearms.......
For CQB, I've always stuck with isoseles when no cover is present. The reason...our bodyarmor will stop 7.62 NATO from front or back, so it makes sense to put the thickest armor towards the threat. Aside from armor...you still want to avoid a sideways penetration of your chest cavity in a gunfight or both your lungs risk being punctured by projectiles etc etc.
When there is cover a weaver stance allows you to shoot around cover, thus angle of body position in relation to threat is dicted by the addition sheilding of cover.
Long story short, from my experience, train to use both stances and other so as to fight proficiently in all terrain.
Train as you will fight...because you will fight as you have trained.......
