Much the same as reported.
My normal carry gun is an H&K USP40c with polymer frame. According to the recoil calculations, this H&K pistol has more recoil than hardball ammo from a standard Government Model.
But it doesn't feel that way to me. They're about the same in practice.
Because the .40 fires a lighter projectile at higher velocity, the recoil of the .40 is a bit sharper - quicker, snappier, more abrupt. That is perceived as being more severe recoil, but it really isn't.
Also, in my estimation, the report is a bit harsher. That also has an effect on the shooter. Nothing that good hearing protection and a positive attitude won't fix.
