Toggle not locking at all anymore?

- Often it is simply a mag that rides too low, if you push up on it and it works- that is the issue.
This may be due to the mag or the mag catch.
- hold open springs, especially replacements, can be too strong
- the button on the mag is too small in diameter on some replacement mags, and original buttons
can be worn, I've seen them flattened from wear on one area, you can rotate the button to a new position

Hope this helps.

DonVoigt, you mention the notch in the bolt may look worn, I have a better photo attached now. No expert but looks OK with a minor wear indication (may be trying to convince myself) the Hold Back behaves ideally when I put pressure on the bottom of the magazine--100% compliance. I've ordered a new Mag as well.

As I look at the old mag I considered wearing away an RCH (very very thin scale of measurement) of metal at the top of the slide. My concept was to mark a thin line with silver sharpie and then grind away with a dremel until the silver ink is gone. The button would now go up just a bit more and press on the Hold-Open Latch raising it up a bit--as if I was applying pressure from below. The only concern I have is the "follower" might rise a similar amount and then cause additional issues. Has anyone tried removing a bit of the channel as I've indicated with any success?
