Hi folks,

Just completed a1911 build (my 1st).  It shoots fine, but I'm having a problem with the extraction of the spent case.  It seems about every 5th round or so the spent case does not always extract.  The case is being pulled out of the barrel, but it does not always "pop" out of the slide.  Does anyone have some obvious tips?  I'm not experienced with 1911's, but I can listen and learn.

One thing I thought worth mentioning:  When I put the slide together I had to ever so slightly pull the extractor back to get the firing pin stop to slide in.  Could this be causing the extractor to be a bit tight on spent casing?  Like I said, this is my first build so I'm just grasping at straws.

I did try to search before asking, but could not find info on this problem.  Maybe I'm not using the correct key words?  If anyone could help or point me in right direction I would be greatful.

thanks!!!!

I'm no expert on 1911s, but my two guesses are either the ejector is too short or the extractor tension is wrong.

That is what I was thinking.  

Does anyone know of spec to use for the 1911 extractor? (and how to use the spec)?  Could I just take a small amount of material off the extractor if it is too tight?  Will it wear in after a while of shooting?

Extractor tension on a 1911 is adjusted by bending the extractor itself.

I would guess this as well.  Or maybe too heavy a recoil spring.  What weight is it, and what loads were you shooting?

ETA:  this "pulling back slightly" of the extractor itself, to get it lined up with the Firing Pin Stop for installation, is perfectly normal.
