I really haven't had a problem with clip latches. I have found that the follower arms do bend and need to be replaced to solve this type of problem.
10X is spot on. Replace the follower arm and your problem will go away.
I maintained 8 M1' s issued to our club by the DCM. We completely shot out the barrels on three which had to be replaced and shot thousands of rounds through the others. Replaced or "hammer adjusted" quite a few followers due to the heavy use these rifles received.
Follower arms wear in the hole for pin that holds bullet guide, follower arm and op-rod catch to the receiver and throws it out of time, allowing clip ejection on 7th round; severe wear can cause clip ejection on 6th round.
This can be corrected by bending the follower arm using a vice or a simple tool you can make (see pics), a brass punch and 2 or 3# hammer and a machinist's rule:
Place the worn follower in between vice jaws (not tight; just close enough together to use as an anvil against the cross pins) after marking near center as shown and measure distance from your jig (or vice) to top of follower @ mark.
Place your brass punch (suggest a bit larger than the one show) at your mark and tap briskly w/hammer; check measurement and repeat until you have bent the follower about 1/32" at the mark. Assemble rifle and test fire.
If still ejects prematurely, repeat above.
Suggest you have a new follower on hand in event you get carried away and bend it a bit too far, but I have yet to need the new one.
Over the years, replaced follower arms, op rod springs, firing pins, ejectors, extractors in that order, but considering the thousands of rounds fired, breakage was very light. Never replaced a clip latch or clip latch spring, though. The Garand is a very sturdy and dependable rifle!
