I have a KT 1911 frame I finished a while back. When I test fired it I ran into a problem I can't figure out.
Sometimes it will not eject the spent casing out. Instead it will stick straight up in the ejection port. I played with the extractor tension thinking it was letting go of the casing before it was kicked out of the slide but that didn't help.
Any clues anyone can offer on what to look for?
Feeds fine and shoots pretty good other than I can't get through a whole mag of ammo on it.
Is your pistol a 5" Govt. model, or a Commander?
What weight recoil spring are you using?
Is your ejector milspec or extended?
It sounds to me like you are short stroking or your ejector is too short/not properly shaped.

Hell, this could be a million things,
1. loose extractor
2. ejection port needs to be lowered
3. maybe need extended ejector
4. take out buffer
5 extractor clocking
6 Check recoil spring, better yet replace it with a new one.
Maybe a few more things but would have to see it, start with the list above and see what you find. What is the measurement when you mic between the bottom of the ejection port and the bottom of the slide, might need to be lowered. Your extractor might also be trashed also or need to be tuned and polished.
It is a government model and it has a wilson extended ejector on it. The recoil spring is the standard weight (16lb if I remember right). No buffer, full length guide rod.
Height of the slide bottom to ejection port is .605.
I haven't tried it with any different weight recoil spings.
Typical recoil spring weight is 18 to 18-1/2 lbs. I've found that when the spent case lands straight up in the ejection port as you mention (stovepiping) it may require a lower weight recoil spring of no less than 16 lbs. for regular boxed ammunition. I've been tuning ejectors and extractors for many years, so when stovepiping occurs. 99% of the time I'm certain it's the recoil spring weight.
Try a 18lb recoil spring, and for kicks put in a new extractor or one out of another pistol.
When I lower ejection ports I lower them to .450 try that also if you have access to a milling machine.
Thanks guys. I will play with sone different springs and a different extractor if I can get my hands on one. Lowering the port will be a last resort as I would hate to refinish the blueing on the colt slide I have on it.
Mine does the same thing. In fact, most times, the cartridge is bent a little where it is hitting the slide.
Here's a link where it was discussed.

I tried an 18 lb spring, and it seemed to dent the casses less, but has started stovepiping.
I looked at the ejector, and compared it with another 1911 that doesn't have this problem. The other is an Officers, so I'm not sure if it is the diference
PICTURE 404
The ejector on the KT is a tad longer than that of the officer that I looked at. I'm thinking about filing the ejector back at the red arrow a bit to see what happens.
Thanks for the link. I have thought about taking a little at a time off the ejector. The extended one makes it difficult to remove a loaded round and have thought that was causing the problem but wasnt sure.
It's not a super expensive part should the experiment not work as planned so it's another idea on my things to try list.
I would be happy if all it did was dent the brass but it usually jams pretty good when it stove pipes.
