while you're at it, change the ejector and spring.

yup, those are the culprits.

also make sure the ejector actually rides all the way up into the channel in the bolt head when the carrier is cycled back.

Is it extracting but not ejecting? On mine, the cases were falling off the bolt head after extraction causing it to jam. Measure the id of the bolt face . It should be near .430 if i remember correctly. A few good jams are enough to weaken the extractor spring as well. If you can move it by hand then you might want to put a new one in.

It should be between .395 and .405

Also, order a 9mm Hammer Spring. My clone came with a 7.62mm Hammer Spring and caused eject/extract problems.

Send it back to Coharie.

Lifetime warranty, use it.

If you start messing with it, they will not honor warranty.

CA is very good with warranty work.
