I bought a Colt LW Commander that supposedly has about 500 rounds through it.
Brought it to the range today and fired about 110 rounds through it (mostly blazer, and some Federal HST). What would cause these two feeding problems: 
Note: Both of these happened after firing and completely ejecting the spent casing, on 5 different mags ( wilson, chip, springfield, and colt mfg.). FTFs were spread throughout it seems, but the one where the live round is sticking out always happened on the last round. Once, it ejected the second to last round after firing and the last round went past the position showed in the second pic and landed on the shooting bench  .
Thanks in advance, This is the first handgun that Ive had problems with, and I own a P22 
ETA: both happened at least 3 times each. |

Check extractor tension and try a couple new mags. Tension could be to tight and the rim of the cartridge isn't sliding under the claw. I just looked at the extractor and it seemed pretty rough where the rim slides in it. Also when comparing it to this: http://www.m1911.org/technic2.htm the gradual rounding doesnt go up as high and the bevel on the lower part of the claw is absent as well. I will check the tension according to that site tomorrow, is there anything else i should know about? Would I be better off buying another extractor and messing with it? |

If it's not even beveled and is rough to boot, I'd just spring for a quality one to begin with. Don't know if you have a small set of files to smooth, angle and polish the old one but a quality extractor is always a good investment. |

Get a new extractor, see if it works, then play with the old one 
Any recommendations for a replacement extractor? This is a series 80. |

Any recommendations for a replacement extractor? This is a series 80. Ed Brown Hardcore. Buy a quality one once. Some of the series 80s [for a short time] were MIM, they went back to barstock because the MIM were POS. |

The last pic of a 'smokestacked' live round, is usually caused by a poor magazine.
Often poor in the sense of a weak spring. The slide is cycling faster than the mag can lift the last round to the mag lips. The last round has the least amount of magazine spring force. This malf is more commonly seen in commander and officers length slides, as their stroke is shorter and they cycle faster. A too strong recoil spring will actually increase the cyclic and worsen the problem 18lb. is correct. I routinely use a firing pin stop with a small bottom radius to slow the cyclic a bit. 23lb. mainspring. The CMC Power Mags have good strong springs. +10% mag springs are available from Wolff for your existing mags. The first jam may be mag related as well.
