I confess I never fired a real gun but I alway thought the recoil came into effect the moment the projectile, together with lots of hot air, leave the barrel.
And thus the moment the barrle could rise it was too late too change the path of the fired shot. At least on single shot.
On full auto on the other hand every bullet after the first would be affected by recoil (from the bullets fired earlier).
If that assumption is wrong please correct me.
back to topic: If I'm GMing I will have all accurate weapons deal additional damage if they are properly braced or, in the case of pistols, the other hzand is not being used for anything else.
And having the bulging biceps talent or wearing PA would not be enough to count the weapon as being braced.
I'd even think about changing the accurate rule as to take a full round action to use.
