You just have to guard that trigger at all cost. I have stuck that Glock in my pants while at home many a times (like when my lady reminds me it's garbage day tomorrow ) without a holster and because I know my gun I just make sure I cover that trigger. So not knowing the the ins and outs of the gun you have is negligent to begin with. It's not the gun, It's the user.I'm a Sig guy, I don't have a Glock. Is it possible to unintentionally fire a Glock based on the facts as have been reported?
