I missed the safety on my Colt Combat Commander back in 82, or was it 83? Whipped it out of the holster, brought it up to the target and squeezed the trigger and got...nothing. Squeezed again....nothing. Looked at the pistol and saw the safety was still on SAFE. Never had missed that little (stock, left side) safety before. No internet in those days. Got out a magazine, made a phone call and ordered a set of extended ambidextrous safeties.
Never missed a safety again between coming out of the holster and lining the sights up on the target.
Just don't have the need for a DA trigger pull. Cocked and locked was working long before I got my first 1911 in 1978. Still works. Like my old 1917 made Colt 1911. Works just as well today as it did during WW1. As nice as mine looks I don't think it stayed in the US Army through WW2.
That's one reason I like the P07/P09. Ambidextrous thumb safeties. I converted my CZ75 Compact to have/use ambidextrous thumb safeties. I like my CZ85 and my CZ75B .40 (I was happy to find out the .40's come with ambidextrous thumb safeties.) I bout that big old XD 5" Tactical .45 acp because it had ambidextrous thumb safeties. I just bought an M&P 5" 9MM in FDE - with - you guessed it, ambidextrous thumb safeties.
I read/see that argument about forgetting the safety. I wonder if there are people who forget to load their pistol before they walk out the door. If there are people who forget to pull the pistol out of the holster if they need to. If they forget to line the sights up on the target. If they forget where the trigger is, or which finger to use to pull the trigger. Or how to change magazines if things get that bad. What else do they forget? Do they forget to change gears when driving? Or to hit the brakes when they need to?
I used to live in WV (miss the hell out of it, too) and we hunted ruffed grouse in/along the old strip mines and tram grades (small rail roads used when they cut the virgin timber back in the early 1900's). If you forget the safety on a grouse you won't get a shot. They are gone that quick. I heard there were people who hunted with their shotgun safety in the FIRE position. We chose not to go to the woods with people like that. People who don't practice/handle their firearms enough to use them instinctively might not instinctively keep them pointed in a safe direction either.
I know a guy who shot himself in the left hand/forearm with a CZ he'd just unloaded. He forgot not to point the muzzle at himself and he forgot not to pull the trigger and he forgot not to insure the chamber was empty after removing the magazine. Is that why they put magazine safeties on some semi auto pistols?
While all the above is true, use whatever you feel comfortable with using. As long as you can hit what you aim at and you know when to aim it and pull the trigger, you can ride with me anytime. You don't have to carry the same caliber/brand of gun I carry.
