But.... But.... Wikipedia says it's a blowback pistolAMA, the P7 is gas retarded rather than gas operated; it's not straight blowback. It's also remarkably self compensating; my former boss claimed you could shoot .380s in them, and he was correct.
The whole squeeze-cocking thing was rather complex, but it surprises me that others have not tried the gas system, as it is relatively compact and doesn't appear to require tolerances tighter than an ordinary blowback gun, save for the cylinder itself.
Perhaps you meant the H&K VP70; it was reputedly pure blowback and quite bulky. The High Point pistols look like a paving brick with a pistol grip; don't know if they actually work, but they are annoyingly ugly, and blowback.
I stand corrected.
I love mine... (gun love, not love love ;-)) love the squeeze cocker - love the trigger - and even though there's no reason to throw 9mm kurz rounds in the gun, it doesn't surprise me that they might work. Just as spot-on accurate as my P5 & P88 too...
