when i lived abroad for a few years i had a Smith n Wesson .38 revovler, thing was big and scary as hell, never had to use it but had to make it known i had it so ppl wouldnt mess around with me as i was living in a 3rd world country and messing with "Gringos" and stealing from them, is pretty commonplace.
Oh and i bought it for $100 from an ex military officer who needed the $ badly. It had no safety was a pretty badass gun overall.
Glocks do not have safteys and that at first made me kinda wierd about buying a gun without a safty. But being the way they are made it is safe as long as one is not in the chamber. It only takes a quick sec to get one loaded so I do not see a downside on this feature. Just one of them things that give the glock there flush look.
