That is quite a statement. Have you ever heard of Glock Leg? Google it and let us know what the first five topics are.

ps Rather than posters asking others to post stats to prove their point of view why not just do some googling on their own and list all their data to illustrate a contrary view.
I will bite. Below is what I googled, the link, and the first paragraph from each site.
http://lmgtfy.com/?q=Glock+Leg
1. Urban Dictionary: Glock Leg.
"A condition where a person shoots himself (or herself) in the leg while holstering their Glock pistol.
This can happen with any weapon yielded by a careless user, but it is common among Glock pistols due to the lack of a
manual safety, relatively
light trigger pull, and
lack of a proper hammer to push on while holstering."
2. Alloutdoor.com: Glock Leg, a condition you don't want.
"It is a reality of life that firearms will go off accidentally. Most, if not all, of the reasons this happens are due to
user errors or a
fundamental disregard for basic firearm handling safety procedures. Many of these discharges result in nasty wounds and an embarrassed ego."
3. Alloutdoor.com: Is DA/SA the cure for Glock Leg Syndrome?
"Bob Owens at Bearing Arms remarks on what he sees as a growing trend among shooters: a move away from striker-fired pistols and back to double action/single action pistols for concealed carry. The reason is the
extra margin of safety these guns give you with that first stiff trigger pull."
4. Calguns.net so how many times has "GLOCK LEG" actually happened?
This is another forum where people debate/dispute the prevalence of glock leg and its causes. I will not quote another forum here.
5. bearingarms.com Maryland Man Discovers "GLock Leg", Public Shame.
"A constant refrain at every gun school I’ve ever attended is that no one ever won a fight or a shooting competition for getting back to the holster faster than everyone else. What these instructors mean is that you should be slow and deliberate in re-holstering your handgun, and that if you feel any resistance at all, you should withdraw the gun entirely and then visually see what is obstructing the holster.
Sometimes that might include body parts."
So using all this unscientific data from the research methods you suggested:
Glock Leg is always caused by poor weapons handling, (inherently a training and competency issue), and is SOMETIMES caused by, hammerless firearms, Light Triggers, Clothing/Body Obstructions, and Lack of a Manual safety.
Its perfectly reasonable to assume that it would usually take a combination of factors in order for an accident to result, and that there would be no one simple solution to the problem of people shooting themselves upon draw/holstering.
Some here have suggested that a manual safety will reduce accidents. The presence of a manual safety does not guarantee its use any more than the attendance of a training course guarantees the eternal perfect execution of the lessons learned. Manual Safeties can be just as prone to the user errors that invariable result in virtually every other firearms accident. The mandatory requirement for a manual safety for the purpose of reducing accidents presumes that the lack of a safety is always the cause, and there are not any other, or better ways to reduce NDs. This is obviously a false assumption. And a dangerous one if you believe that simply adding safeties, while ignoring the rest of the factors that play a part. If so then you are probably worse off then you were before, but possibly feeling a bit better wrapped in your nice cosy false sense of security.
If you address the critical factor first, poor handling, then the manual safety becomes almost irrelevant.
"I shot myself in the leg when holstering my pistol. My finger was on the trigger because I thought it was unloaded, and it got snagged in the holster and tripped the trigger. Clearly my not paying attention to what was going on, lack of awareness of the state of my pistol or my finger being on the trigger was not the problem. If only I had used the safety this would not have happened", said no one, ever. # ridiculous.
