But in that case the empty case would get stuck, not the new round. So, it expands to snugly fit the walls of the chamber. Brass is better at this sealing action because it is more malleable than steel. Thus you have less blowback into the chamber and the receiver. gun can be fired equally well and safely by a percussion tube. A squib is a round that does not have enough powder charge to send the bullet down the chamber and out the barrel.

If there is too much play, the magazine will hang too low and the next round will not be stripped from the magazine correctly.Īnother problem that will cause weird extraction and feeding problems is the little spring beneath the extractor. The magazine has a catch (opening) in the side where it is held in place by the magazine button in the pistol. You may also want to look at magazine placement and height. As a result, most American ammunition is too short for the luger. This is the result of SAAMI specs, where the maximum SAAMI length is actually the MINIMUM DWM/Manufacturer's spec. The symptoms you describe also happen as the result of ammunition whose OAL (overall average lenght) is too low.
