Therefore, you should have someone else put a few rounds through your gun to see if that person also experiences malfunctions. It is best to hand your weapon over to an experienced shooter, as he or she will be familiar with the concept of limp-wristing and thus will retain a firm grip on the weapon. If misfeeds persist, even after the break-in period and handing the gun over to a friend, you might want to start replacing parts instead of enduring the long wait to send the gun back to the factory. I find that the source of most problems with autoloaders lie with the ammunition and the magazine, in that order. Only after exhausting the possibility that those two are not the culprits will I send the gun back to the factory.
Many guns are ammunition sensitive.
Yeah, we hear talk about Glock perfection and how SIG s and Rugers can digest anything that comes out of a factory box, but the bottom line is that some guns are ammunition sensitive. So if your gun jams with Remington UMC ammunition, try some American Eagle. I have an AR-7 that absolutely refuses to digest Federal ammunition, but runs without a hitch when Winchester or Remington high velocity ammunition is used. The same applies to hollowpoint defensive ammunition. Try out a bunch of the premium defensive loads, and stick with the one that your gun can fire around 100-200 rounds without any hangups.
