I just bought this model 90 octagon 22LR . It picks the cartridge from the mag and chambers it 

but only ejects it on the second pull of the slide and sometimes leaves it on top of the lifter.

I’m thinking that possibly somebody may have changed the lifter for a different caliber  but the depth of the lifter chamber looks correct . 

Can somebody tell me what changes were made in production to use the Long rifle cartridge in the model 90 ? Is the Bolt the same as Long & short ? I know the lifter is different for each.   

Thanks

Hi Wayne,

The 1890 bolt is the same as the Short and Long, the only significant difference is the lifter and of course the chambering and rifling twist rate in the barrel.

There is a small flat spring on top of the finger on the lifter, when it gets weak or broken it can cause the symptoms you describe, check it first.

Make sure you look at how to remove the bolt if it has to be removed to work on the elevator?  First and only time I removed a bolt was when I had to replace the extractor.  There is a slight trick but I don’t remember what it is?

If the spring is intact but just flattened you can test to see if it is the problem by putting a new arch in it with needle-nose pliers.  It won’t stay arched long if it is fatigued but should be ok for at least a couple of cycles for testing purposes.

I have the bolt out by removing slide arm retainer and gently lifting slide arm out of 

bolt groove and lifting and sliding bolt to rear. The spring is very weak and I have a new one comming from a friend this weekend . Will see how that works.

Thanks
