We spent Thanksgiving out in the country with my family. This provided the perfect opportunity to do a bit of night shooting to check the muzzle flash on three 9mm loads. I haven't really done any dim light shooting since I retired. The loads were the Remington 147 Golden Saber, Speer 124+P Gold Dot (what I usually carry) and the 147 Gold Dot. What I saw didn't match my expectations. In order of most flash, I expected Golden Saber, +P Gold Dot and lowest from 147 Gold Dot.
Surprisingly the 147 Golden Saber had significantly less flash than the Gold Dots. The 124+P and 147 Gold Dots were undistinguishable.
In the past, the 147 Golden Saber seemed pretty bright. Last night it was both smaller and dimmer and than either of the Gold Dots.
Having said that, neither of the Gold Dots were bright enough to be overly distracting or cause loss of the HD sights on the 226.
