Lots of folks think the same as you regarding the lack of an actual safety so I understand.
And for a novice shooter you are right that it does create or increase the likelylood of a negligent discharge.
Another issue with the Glock is the trigger pull which is much lighter (5.5 lbs) than your typical double action revolver or say a DA/SA Sig where that first double action pull is 10 lbs.
A benefit of that however is that the trigger pull is consistent and Glocks have short resets so follow-up shots can be got off quick. Especially if you train to not release the trigger all the way after the shot. Your average shooter doesn't take it to that level let alone train.
I cringe and actually get nervous at the range when other shooters are there and I see there complete lack of trigger and/or muzzle discipline.
Straight trigger finger is and will always be the best safety there is. Unfortunately most people don't do it.
I've been looking for an old school 1911 but they are hard to come by in CA. The classic Colt 1911s are all off the CA DOJ "roster" so the only way to acquire one is to find a used one already in state.
And if you have one you either (a) dont want to sell it or (b) will only sell it at a huge premium.
Surprised you find the grip fat on the P226. That's my favorite grip of my semi-autos. Better than my Glocks.
I suppose if you have 1911s though that is your reference point. My 226 gets compared to the Glocks which definitely don't compare to the 1911 in terms of grip feel.
You dont happen to live in CA and want to unload the 1911 do you??
