Yes! At some point I will own a G23C. I've shot them before in lowlight, and amazingly was not blinded the "flash." The only time I noticed it was when I was actively concentrating on looking for it, as opposed to focussing on my front sight.
I've shot 4" .357 magnum revolvers with quality ammo during daylight hours. The FIREBALL that emanated from the cylinder gap, and the front of the barrel was HUGE and quite noticeable! No I wasn't blinded then either, but I have to wonder what it may have been like in a lowlight scenario.
