The safety can't be set to "fire" one-handed by right-handed shooters. It requires two hands if the pistol is in your right hand (as God intended).
It can, for the 10% of the world who are lefties, with a simple extension of the index finger. Score one for the mutants (my MIL, wife, and daughter are so afflicted).
If you are hunting rodents at varying ranges and have both a carbine and a pistol, and go to draw your pistol with the right (after transferring the carbine to the left hand), you must make a very awkward move to flick the safety off with your left thumb, while holding the pistol in the right shooting hand, all while juggling the carbine. This may actually cause your pistol and rifle to clash with attendant noise and damage.
A mouse is alive today because of this.
This air weapon is useless for self-defense in close quarter action scenarios. The safety should either be reversible, or a simple button in the trigger guard, not up forward on the left side of the pistol requiring two-handed operation. No telling how many airgunners have been felled by charging mice when relying on their sidearm, but the potential consequences are dire. The HW40/P3/P17/Marksman 2004 is a much-admired platform, and I have not seen this deficiency discussed before.
The Weihrauch company should address this oversight immediately. 🙂
