Are springers stuck in the 80s?

[look no hands]

It just doesn't have the resistance of say, an old school HW77 detent. I would like more resistance!

I came across a 25-round 50 yard still-air group I shot with that ProSport of yours, by golly it was accurate. I will spec it up when I get hold of some vernier calipers.

And you got rid of it

If I remember correctly didn't the early 77 have a sliding type catch underneath?
