Iv'e Never had a jam/failure to feed or failure to eject with any of my Glocks in 9mm,.45acp, Models 17,19,26 and 21,30. Glock is not paying me by the way to promote them they should hehehehe. I have had jams with HK's expensive 1911'S,Sig Sauers. But the only other thing i can think of never jamming is my S&W 686 .357magnum Revolver Now i know why my Grandfather preffered Wheel Guns. But yeah i believe that Revolvers truly are the only thing that will go bang every time. Other than my Glocks Anything can fail keep in mind but with magazine fed semi's you have springs of the magazine and feed ramps and quick action extractors. As well as numerous parts that can fail the more parts you have the more potential problems that can happen. I have fed dirty just disgusting ammo that was cheaper than a penny through my Glocks and never one failure. Believe it without cleaning for over a year there myth busted i can vouch for it. Anyways if you think about it all you have to worry about in a Revolver is a DUD PRIMER AND OR DUD POWDER. I have never heard of the Cylinder Locking up on a Revolver but i guess anything can happen. In a Revolver I have heard of a chamber not lining up exactly with the barrel and a round exploding because the bullet hit part of the barrel wall. That is the only catastrophic failure i can see happening with a revolver. But other than that you pull that trigger the cylinder revolves,cocks the hammer and drops the hammer every time. How do you guys feel about a Revolver for a go to Gun?
