So what would Farnum call the devices on my Para LDA? (Note that on the Para, the hammer is always down - i.e. it cannot be cocked - except when the trigger is pulled to fire the gun.) As far as I know, they consist of:Firearms can have multiple devices intended to improve safety, like the Glock Safe-Action trigger, beaver-tail blocks, the Kimber Series II firing pin block, or the "magazine safety" mentioned earlier. But a safety is a singular device that is specifically designed to prevent a cocked hammer or striker from falling so long as that device is engaged. Handguns that have a safety are correctly, optimally carried with striker or hammer cocked, and the safety engaged. That's what they're made for.
1) A device that Para Ordnance calls a "grip safety" that functions similar to that of a 1911 pattern gun.
2) A device that Para Ordnance calls a "manual safety" that is frame mounted and looks like the safety of a 1911 pattern gun, but functions such that when in the raised ("safe") position the trigger is completely disconnected from the hammer and can move freely through its entire range of motion without having any effect whatsoever.
3) A firing pin block that is generally similar to a Colt Series 80 in that it consists of a slide mounted plunger that blocks forward motion of the firing pin unless the trigger is pulled fully to the rear.
As an engineer by profession, I am used to using precise nomenclature to identify or refer to the various parts of a machine or device when communicating with other engineers. Generally, the authoritative sources for this nomenclature are the manufacturer's engineering drawings, data sheets, and manuals. It does me no good to refer to something as a "mainshaft Timkin bearing", even though it may be exactly that, if the manufacturer calls it a "mainshaft roller bearing".
BTW, I am not taking issue at all with Farnum's position on the proper way to carry the Beretta. I think his analysis and advice are 100% dead on in that regard.
