The Weaver stance came about to control muzzle flip (recoil) and to get a quick controlled follow-up shot. One aspect of the Weaver Stance is the two handed hold of the handgun. The strong hand arm pushes forward as the weak hand pull back against the strong hand. It is an isometric exercise which pretensions the arms including the wrists to reduce muzzle flip. This allows faster follow-up shots.
I don't want to turn this thread into a debate about stance, but the Weaver stance assumes you can and ought to prevent muzzle rise by physically overpowering it in the first place. But what's been found since the Weaver stance developed is that it's not the muzzle flip per se
that slows followup shots - the muzzle rises and falls quicker than most realize. What slows down followup shots is when the muzzle doesn't return to it's starting place, in which case, the shooter has to take the time to figure out where the front sight is and how to get it back (assuming they're even looking at the front sight). This is a grip issue, and the fastest shooters (e.g. USPSA, IDPA, Steel Challenge) universally agree a proper neutral
grip is what allows the muzzle to return consistently. Sight picture is still important, of course, but it only takes the shooters an instant to re-confirm it before getting off the next shot.
A neutral grip is firm, but it's neutral when one hand isn't in opposition to the other (check out BE's pic in the Enos link above). IOW, remove one hand, and the gun shouldn't move. It's easiest to achieve a neutral grip in an isosceles stance, which is why you'll see all top competitive action shooters using an isosceles.
I agree it's tough to offer advice without seeing you shoot, but my generic advice is to stand squared to the target, slightly lean forward & bend knees, then grip high, firm, and neutrally. Confirm your neutral grip by watching the front sight to see if it's coming back to it's original position. Once you get your neutral grip established, just break the followup shot the instant
you confirm sight alignment. To be done well, it'll require that your visual cues, your brain, and your trigger control are all in sync, which requires lots of practice.
