So am I. Just not a chambered weapon with no external safety.
All of my pistols are DA only pistols with no external safety except your finger off of the trigger. Works for me. The triggers are so heavy, there's no way you could accidentally pull it.
"... Just not a chambered weapon with no external safety." I once felt like you did with my Glock, but never went so far as to not have a round chambered.
When the worry became unbearable, I put my Glock in the safe and got a 1911.
My first generation Glock 17 is available for sale if you'd like one for your other hand. Inquire within.
