Bit of an update.
16lbs recoil spring too much, pushed Federal 230 FMJ RN more so than usual into case mouth.
Went back to original spring.
Received Triple K mag. Very different follower than original mag, good lips.
Still have issues with some bullets getting hung up on feed ramp and some rims stopping on hitting follower and case mouth of next round.
on ejection. Have tried polishing feed ramp, will try more aggressive angle.
Extractor seems to be in decent shape, I.E. without excessive wear, but I wonder if it has too much slop to hold rim firmly enough.
Time to try some Hornady cone shape bullets.
Original on left, Triple K for Llama IX-A middle, and Chip McCormick for Colt 1911
Note wide base plates on Llama mags. Regular 1911 mag would need the the mag latch opening move up a bit to lock up.
both Llama mags seems to have some up and down play when supposed to be locked up.
Had to do some grinding on the grip screws. Some were just a bit too long and dragged on magazines
and had to sand a bit off back of one grip panel for interference with new mag base.
There were rough edges on trigger stirrup dragging on mag so I stoned them.
