I just posted this in your other thread:
"It depends on your comfort zone,and the Glock/safety issue is a catch 22.
Safety has to be ingrained in that finger to run a Glock,remember that quite a few Glock NDs are when cleaning-a round is missed in the chamber and the trigger has to be pulled for takedown,oops that hurt.You'd be surprised how many people have brainfade and rack the slide before dropping the mag.
On the other side,you have to have the act of taking off the safety ingrained just like the trigger finger.I've carried and shot a shtload of rounds through 1911s for a long time,I have never missed the safety or had it cost me a hundredth of a second on the clock,contrary to the naysayer's opinions.
What you need to do is figure out which you're going to be cool with.If that finger can be contained go "safe action" striker fired,if you think you need to play it safe go with an easily manipulated safety to help ingrain the basics so the safety rules are subconsciencely covered.
In Glock vs 1911 debates I give this example:
A Glock fires by pulling the trigger through a kind of short pull that can break at under 5lbs up,boom.
A 1911 fires by gripping to deactivate the grip safety so the trigger can move and take the thumb safety off.While the pull is shorter,a nasty GI trigger can have a lot of creep and stack at 7lbs easily,boom.
Is there really much difference between the 2, that a 1911 carried with the safety off and a Glock, are operating so close to the same that it isn't really different?With both in that state of readiness,I can make the Glock go off and the 1911 can't.
Pick what's in you comfort zone,proficiency takes time and practice."
From reading this one,go with a safety for now and familiarize yourself more with the differences between operating principles.All autos you will either rack the slide or drop it from locked open after inserting a mag.At that point things change.On a Glock type gun you don't touch the trigger until you need to hear a bang,decock to be basically like a revolver,or put the safety on to block the hammer from falling until taken off.
I have a Beretta 92 and love it,but I don't prefer the slide mounted safeties because it's an unnatural move for me to take it off.I can and don't have a problem with it but it's odd for me.I prefer frame mounted safeties/decockers,it's a more natural act to operate them.Your choice though.
