I only like DA/SA guns for self defense at this point in my life... Any other type of trigger (Glock/XD/PPQ, etc) is for range use only for me... The whole "the real safety is between your ears" mentality is real easy to say... until the adrenaline kicks in during a real situation.
I've previously carried 1911s and Glocks for years. However, I am somewhat at a different point now... After all these years of carrying and owning different guns (I have owned a LOT of different platforms).... I don't like Glocks type guns for self defense anymore...
I had a near robbery in the parking lot of my local gunstore a little over 2 years ago. I saw the situation happening, and I managed to avoid the guy and cut through some cars and jumped down a level in the parking lot. The guy cut off pursuit of me after a few moments.
All I had was a Keltec 32 in my front pocket, as I was taking my Beretta 92 into the store to try it for laser grips... (it wasn't yet my carry gun anyway) So, I was walking with that particular gun inside of a gun case.
I kept my wits, but the situation showed me what it was like when the adrenaline kicks in. Your thought process changes. It's not the same as all the practice you put in at the range - or how you THINK you should or will react in a situation.
I also had an old friend from when I was a teen (hadn't seen him in many years) - I recently found out a story about him that happened a few years ago... He apparently was getting car jacked (back in Louisiana), and he grabbed his gun from the center console as he started to comply to get out the car. Guess what he did... As he swept himself with the muzzle to bring his Glock in an aiming position, he shot himself in the knee/leg. Boom... Now, he walks with a limp all the time and can't get around well...
Dumb? Yes. Can I see how it could easily happen in a super high stress situation? Yes, I can. Especially after seeing how your thoughts change during the adrenaline dump... Plus, look at all the accidental discharges that are stupidly done by law enforcement officers who carry Glocks. And, people ARE people. We all screw up and make mistakes throughout our lives, even with stuff we practice. So, it's easy to say "the real safety is in your head" - but people mess up sometimes in normal situations each and every day doing stupid stuff (we are human)... What could happen in an adrenaline dump?
After my personal experience event, I re-evaluated some issues with my carry gun. For a while, I temporarily switched to a 45... I'm back to a 9mm now. But, I no longer carry a gun that needs to be cocked and locked (1911, USP compact that I sometimes kept cocked and locked at the time). I use/have used so many different platforms over the years that I don't want to stupidly forget to deactivate a thumb safety (I'd need to get back to 1911s exclusively for a while to get back into the habit of it).
And, I also got rid of the Keltec 32... I REALLY, REALLY felt bad in the situation thinking that all I had to defend myself with was a 32 FMJ round. (32 JHP isn't really as effective in that caliber as FMJ)
I also will no longer carry a gun that has a trigger like a Glock, M&P, XD. That short, light trigger too easily could replicate what happened to my friend shooting himself. Also, I get my untucked shirt caught in my IWB holster somewhat frequently when holstering/reholstering at home...
Do this with a Glock - boom.
Do it with even an XD (with the grip safety) - boom (one would probably have their hand in place over the grip safety while holstering).
Do this with a 1911 - and forget to reactivate the thumb safety even ONE time - boom.
The DA/SA trigger of my 92... I do try to be careful, but I know there won't be an A/D when I do this or when I try to clear the shirt from the holster...
Am I over worrying about this situation? Maybe. I admit that I carried a Glock 26 for 8 years previously (OWB or in my pocket, though - not IWB). I also once carried a 1911 (OWB - not IWB). But I’ve owned tons of different guns since then, and my preferences and ideas on the issues have changed.
That experience "I" had showed me I wanted a gun that I could pull and shoot - without deactivation of anything... But, I also didn't want TOO light/short of a trigger. So, the DA/SA trigger is my preference now. And, with a "D" spring, the DA pull of my Beretta 92s are down from 11.5+lbs to 8.2-8.5lbs. Still heavy enough (and long enough of a trigger pull) to keep me honest. But, not too heavy.
I also never hardly EVER practiced my first shot in double action on DA/SA guns I've owned over the years. Nor, did I practice 1 handed shooting. Since that near robbery experience, I have done both. I do it a LOT.
My issues that I personally have stated above sorta keeps me from buying another Glock, or another XD or an M&P or a Walther PPQ as well - as without a DA/SA trigger, it would always be delegated to just a range toy... Not for carry usage...
Besides the PPQ, I REALLY like the look of the 9mm XDm with the stainless slide as well. I may or may not buy one eventually. But, I'd never carry it for the lack of DA/SA.
Anyway - I'm not telling ya what to do. Carry what and how you like. Disagree with my personal decision... That's fine... Just throwing something out there for some people who may not have considered some of these issues...
