Now I carry glocks and other pistols with no external safeties, but I'll be the first to admit that the statement above is untrue. Cheap or worn holsters can get in the trigger guard and cause the trigger to be depressed. It can happen. It is still a user induced error that is completely unavoidable with common sense, but it is still something that can happen without a finger. It isn't a problem limited to glocks, though.
Just a friendly challenge, here.
Can you cite a reference for your opinion on this? Maybe an article or some proof that this has actually happened?
I only ask because I have tested, many times, many ways, the Glock trigger safety and come to the conclusion that it's 'Highly' unlikely that something can get:
1. into the wide trigger guard 'enough' to fully depress the trigger enough to discharge the gun. (We're talking factory trigger weights here. No lightweight competition triggers.)
OR
2. into the wide trigger guard at the 'correct angle' to depress the small safety on the trigger and 'maintain' that angle while depressing the trigger straight back enough to discharge the firearm.
Remember this would have to be an object flexible enough to accidentally find its way into the trigger guard from the side and, somehow, have the stability to depress a ~5 lb trigger while maintaining the correct angle to do this 'straight back' all at the same time.
If you can present convincing proof, then you will be helping me and any others who are unaware of that danger.
I have put an unloaded Glock into my pants Mexican style and tried to completely pull the trigger through my pants, tried to hang the trigger with string (thread to twine) and many other unsuspecting items just to test the possibility of the gun ever accidentally being discharged by a random item either in the holster or some other place.
While not impossible, it is very difficult and, likewise, unlikely to line up all those things to make the gun discharge.
I would be interested to know if a tattered holster could actually accomplish this.
Always interested in good information is all.
