I've never understood the logic of people who have absolutely no problem carrying a revolver with all cylinders loaded, depending only on the heavier double action trigger pull to save them from ad/nd's yet quake in their boots at the thought of doing the very same thing with a pistol..
It's all about the first round heavier DA trigger pull. Period.
I love both of my P99/AS's... I know for a fact that I have to do something absolutely stupid to overcome the approximately 8+lbs of trigger pull on the first round for the pistol to fire.. It simply cannot fire itself. AFTER that initial 8+ lb. trigger pull I then fire the rest of the rounds single action at approximately 4+lbs..
Learn to keep your index finger off the trigger/striker until you actually are determined you must shoot something.
I know this discussion did not start involving revolver/pistol senarios, but sooner or later someone is going to bring it up, so I just got it out of the way.
I would not be comfortable knowing I had to rack the slide whatever distance it took to cock a "decocked" pistol in a crisis.. No thanks.
I'm almost 65 years old. I've been cc legally for over 40 years, and for many years my cc firearm of choice was a snubby 38cal revolver. I never gave a second thought to the fact that the only safety was the da trigger pull.. Of course that was the safety, that's the way it was designed. I most certainly never carried that sucker cocked.
I think the Walther P99/AS pistol is a fantastic firearm.. I carry either my compact, or full size in a FIST Kydex IWB holster. Uncocked, but with one in the chamber.
In a crisis I have no doubt I can overcome the da trigger pull of the first round, and then I will be comforted in knowing each succeeding round will be SA..
IMO, IMO, carrying a modern DA/SA pistol is as safe as you would want it to be, and unless you are dumb enough to keep a loaded pistol cocked you should never have a problem.
Don't carry a cocked firearm unless it was designed to be safely carried "cocked and locked" as with the Colt 1911 45cal automatic. I never even got comfortable doing that...
Keep your finger off the trigger.
Use a good holster that keeps the trigger covered.
That'll about do it..
