Does this photo answer your question? On the right is 2015 83 I have carried for a few years, on the left 2021 83. Not a perfectly square angle, just leaned against each other for this pic. There has to be room for the lock spring to move, so they both have a small gap. Never noticed before taking this pic for your question but close examination shows the 2021 spring to be slightly longer, it follows the curvature on the end before the gap. While the gap on my example is larger on the 2021, the longer spring is probably an improvement as it will likely be less prone to clogging with crud.
Crescent and long pull in the closed position. Prefer the long pull, more accessible. You can see how much closer the crescent is to the handle than the long pull and prefer it's aesthetics.
