denfoote,
Yep, it's at least 100 lbs, maybe more.
I was thinkin' (always a bad idea) about making a small winch the size of a spare mag you could carry... just fit it over the grip and turn the handle, and it'll drag back the slide and let it pop forwards at the proper time...
I think what you're saying, basically, is that it's a major pain to chamber a round. The slide stop would make it easier. Right?
The way I now cycle the slide is to approach it like an enemy. I grab it with the entire palm of my non-shooting hand, wrench it back as hard as possible, and let it slip through my grip as it reaches full travel.
This never fails to chamber a round.
Sometimes it also requires immediate medical attention.
You may leave a bit of your hide on the slide serrations, but you'll be ready to go bang!
