Toggle sticking open

The only resistance one would normally feel would be when the breach bolt engaged the ejector spring when reassembling. Anything above that and I would start to think about the re-barrel warping or altering the fork positions. Grab a caliper and measure the distance between the forks to check for warped forks all along the forks front to back. It should be around .51" give or take .005" but most importantly they should be the same distance all along the forks, front, middle and back, any noticeable distance change would indicate a warped or 'bent' fork. You also must check the vertical orientation but if it was a vertical aberration you would most likely notice that the axle pin would not fit smoothly.

Again though, I would start with the mainspring.

Good luck Mark.

Spangy,

I measured and it is indeed .51. to be exact the maximum "run out", to incorrectly use a machining term, is about .005" or so, so by your numbers it is within spec. Axle pin goes in and out freely.

I'm going to order up a Wolff Gunspring kit tomorrow morning.
