A polymer framed pistol does not and can not duplicate the balance and recoil handling of an all steel pistol...
I'm sure your point about balance is valid, but I've never noticed it in real world conditions or in competition. In fact, in competition, I've frequently gotten my best times/scores using a Glock 34 or 35. I do almost as well with steel framed guns, but I'm just a hair quicker with the polymer guns.
I understand that the experience just described was just ME
-- but a lot of the claims made here about polymer- or steel-framed guns are really similar "just ME
" claims made by a different "me."
In terms of recoil, the slight flex in a some polymer frames actually makes recoil less noticeable and better-handled in those guns than in steel-framed guns.
