Take down lever (which way?)

Obviously if your toggle assembly is not going back into battery the mainspring pops to the top of the list.

If the mainspring is out of the gun is there a compression test that can tell you if it is stout enough?

Gary,

If you search around the site, you'll find a thread that discusses this and there were a couple proposals and attempts to gather comparative measurements of the strengths of installed mainsprings. Most involve a simple scale and some way of connecting the acton to the scale. One way was to insert a wooden dowel down the barrel and measure what it takes to move the action while pressing the pistol down onto the scale with the dowel sticking out enough to be what is moved. The other way was to put the pistol into a padded vise, muzzle up, and measure what weight pull was necessary to pull the toggle back connecting the knobs to a fish scale with a cord--which would not m,ar the finish.

You'll be able, either way, to compare installed spring strengths using the data achieved. So, no need to invest in anything extra...

D.P.
