I touched on this once before on CombatCarry (as part of another thread) but, not sure that it ever reached any completely satisfactory conclusion.
How did the misconception get started that wearing a holster that covers the firearm trigger & trigger guard helps prevent negligent discharges?
I thought that the shooter keeping the trigger finger out of the trigger guard & off of the trigger was what prevented negligent discharges.
Pretty much all negligent discharges happen when folks are fiddling with their firearm outside of the holster or cleaning the firearm or while reholstering the firearm. Most Often ND's happen when the "UNLOADED" firearm turns out to be loaded.
My "thought out logical opinion" is that a negligent discharge is actually MORE LIKELY to happen with a "covered trigger guard" holster - if the index finger is inside the trigger guard while reholstering the firearm.
It is then that the leather or Kydex holster material in the location of the trigger & guard (the material that covers the trigger guard) that forces the trigger finger up to operate the trigger.
Can you picture that in your mind?
No solid material covering the trigger guard area equals nothing to force the finger upward to contact the trigger and discharge the firearm during a Whoops!
Also...having the trigger guard covered on a holstered single action revolver does nothing since the firearm is carried hammer down & the SAA must be "Thumb Cocked" in order for THAT firearm to discharge.
Holstering a "cocked and locked" 1911 pattern pistol is also no safer with a covered rather than uncovered trigger guard.
Since you can squeeze the trigger until your index finger turns blue and with the thumb safety engaged and that firearm still will not discharge.
I've also heard is said that having the holstered in a rig with the trigger guard covered prevents something like a tree branch from entering into your holster and pulling your trigger for you. A guaranteed quite unlikely scenario for any street carried defensive firearm.
I can see how LEOs that carry in any Threat Level Retention holster would want the trigger guard covered AKA during a Gun Grab the firearm stays locked & hopefully securely contained in the holster with the guard & trigger covered.
That sounds logical to me even though most Serious Bad Guys have the workings of the retention style holsters pretty much all figured out by now.
So...while I sure don't (In Any Way) want to change the design style of any modern holsters. Nope!
That's NOT my intention at all.
I DO think the Safety Aspect of having the trigger area always covered has been greatly magnified way out of proportion during the past 20 some years or so.
I do see some advantage directly related to "Holster Construction" of having a solid continuous opening to the rig - to aid in preventing possible holster collapse. That makes sense.
Placing the trigger finger in the guard and/or on the trigger prematurely (either while drawing & presenting or reholstering) is a Shooter Technique Issue and NOT a holster or equipment issue.
More careful practice and a hard review of the Safety Rules & Regs solves that particular problem.
There are already so many unnecessary and silly restrictions placed on shooters from "outside forces" that I hate to see us over~restrict ourselves because some Guns & Ammo Gunwriter Myth took root, budded and blossomed 20 years ago.
OK...now I'm all braced and ready for all the Knee~Jerk impulse reactions of:
"Well, I'll Still Always Carry With The Trigger Guard Covered."
Guess What? ~ With modern holsters...you really don't have a choice anymore....anyway!
That was not my point.
My point is that it's really not the big, huge, deal that so many people make it out to be from a Firearm Safety Standpoint.
The only real reason that I am even posting this thread is that on the various gun forums...I must hear the same old diatribe safety~mantra of the "holster w/ covered trigger guard" preventing ND's at least 100 times per year. It's such an illogical statement.
So what is it? Is it a "feel good thing" because some shooters do not trust themselves to just keep that finger out of there. Afraid you might forget? I'm just honestly curious so fill me in and/or tell me where I'm wrong.
Just my personal opinion.
Yours is always welcome...feel free to post your thoughts.
By The Way...The most common holster related ND (that I've read about in recent years) is reholstering and shoving a DAO Glock back into the rig...with the trigger finger still inside the trigger guard.
In that particular unfortunate happenstance - having NO material in the holster trigger guard area would actually PREVENT that ND & would not cause it.
