I have a Springfield Armory V10 (Officer's Model clone) that I've had for about 4 years now. I shoot it every once in a while, and haven't had any problems until now. It has about 1000 rounds through it. All of a sudden, I have FTEs that I haven't seen before. The empty brass gets halfway out of the chamber, but the next round in the mag stops the empty from coming out all the way. It disengages from the extractor (yanks it out from under the rim actually), the slide continues back, then jams against the base of the next round as it tries to feed, but it can't feed cause the empty case is still halfway in the chamber. I probably get this with every other mag now.  I get the same FTE with both factory mags, and with some aftermarket 8-rounders. I also got it today after a thorough cleaning. I just detail cleaned it again, I pulled the extractor out, inspected and cleaned it, cleaned the bore it rides in, lubed it with teflon. It didn't look damaged, worn or bent. Any ideas? This is my carry gun, and now I'm a little sketchy on carrying it until I get this thing working reliably. Thanks. |

Alwaya the first place to start. Use a .22lr brass brush in the extractor channel to ensure that you have no hardened carbon buildup in the channel. If it turns out that the extractor channel is clean then you need to look at the extractor. check the FAQ at the top of the forum. |

How much tension does the extractor now have? Can you load a live round onto the slide alone (off the frame), and have the round stay on the breach face from the tension of the extractor? If not, then you may want to to increase the extractor tension (just enough to hold the round, and not more). Also to point out, at the 1k mark, you should be on your second replacement recoil spring (read this may be the problem in it's self if the extractor spring tension is good). |
Ah HAH. There is probably a millimeter of space between a round and the breech face. That may be it then? I'll check on the extractor tension. Plus get a new set of springs. Thanks.  ETA: This is the malfunction, from the FAQs. Looks like a new extractor is in order.

Could be that the extractor was never set right to begin with (both contact area and tension). To reset the tension without an extractor bender tool, stick the extractor backward into the slide chance and tweak/bend it stronger. Again a little goes a long way so don't just go buck wild and way over tension it to begin with. Lightly bend it more, then retest with a round until it will just hold it to the breach face. If you over tension the extractor, then you end up with three point jams since the case will not slip into position at loading (read extractor will not budge/flex out to allow the case to slip up into the extractor groove). As for the contact, the rim of the case should be the part being retained but the extractor relief channel (not the claw tip touching the side of the case), so if needed, take the extractor pad below the claw down a bit (rounded over portion) to get the correct contact if tension tweaking alone does not solve the problem. While you at it, check and set/bevel the groove entry lip, and even the claw entry point if it was not beveled as well. Worst case, the new tweaked extractor only last a few hundred rounds, but at least you have had gotten in a dry run as setting the new one. Also, the current extractor metal is probably worn out or soft at this point (it a SA officer unit so that’s a given), so yes, a new extractor is in your future for a permanent correction to the problem (until that one gives out, and it you buy a descent one (read bullet proof), much longer down the road the old stock one at a 1K mark). www.m1911.org/technic2.htm |
