No, it's 4 dB A louder with the cocking aid still attached. I gave distance from muzzles as 4 ft, and height above ground as 1½ ft, but omitted to say that the Tenma meter was in a general position in front of the muzzle.
I would not enjoy using the Scorpion without using (then removing) its cocking aid. Now I find it easier to shoot accurately than the HW45 glow-sight job, but which is louder, smaller and lighter than the Scorpion.
Yep, Scorpion.
