I just dont like striker-fire guns for DC. the glock is the shovel of auto pistols and the PPS is a great ultra concealable gun, but as wonderfully great they may seem for DC, that striker-fire system makes them a no go imo. fact is, if you are unlucky enought to have to use your CC gun to defend yourself, then you may just be unlucky enough to have a dud chambered and ready to fail you.
now if you have a DA/SA or DA only gun, you can simply pull the trigger again and 99.999% of the time that will make the dud fire and boom your back in action.
sure you can say, well, all Id have to do is pull the slide back and load another round. great! but what if your off hand is unavailable? what if all you have is 1/2 second to react? you can pull that trigger 3 or 4 times in a second easy, can you pull the trigger, action the slide(assuming your off hand is available) and pull the trigger again in 1/2 second?
just my $0.02
now let the hate pour on in I can already feel it coming
