Help with a .32 HE again?

[forindooruseonly]

Please forgive my ignorance on this and help me out.

When reassembling this, the hand isn't held in place so that if the barrel is pointed up, the cylinder will not rotate. If it is pointed down, the hand will grab and the cylinder will rotate. What did I leave out, or do wrong?

I'm not familiar with this style of 5 screw gun, and I think it has something to do with the flat spring on the sideplate pictured, but I'm lost.

I stupidly lost the bolt plunger and had to wait a couple of weeks for a replacement. I am not sure if I forgot what I was doing or lost another part in the meantime.

According to the Kuhnhausen shop manual, your revolver has what is called a "Type 1" hammer block mechanism. The tab on the spring loaded/staked in hammer block stem located in the sideplate interfaces with the cam located on the rear edge of the hand. This interface between the hammer block (spring loaded) and the hand tensions the hand forward. At the same time, the upward movement of the hand during the cocking phase, pushes down on the hammer block cam and disengages the hammer block flag....pushes it back, (into the slot in the sideplate) so that the hammer can fall fully forward when the trigger is pulled.

Are you not able to get the sideplate back on? Is there outward, spring tension on the "staked in" hammer block stem?

Actually it's the Type 2 which does not supply spring tension to the hand.

The hand gets it's tension from a coil spring in the front of the trigger* like this:

So your hand is not installed in the trigger correctly.

*Not to be confused with post war triggers which have a spiral hand spring in the center rear of the trigger.

Thank you! I appreciate both of your help very much! I will update when I get a chance to get it back together.

The spring shown in your photo below looks like it might be from your trigger. Was it installed when you assembled and tested the gun?

I've got it back together and working, thanks to your assistance. Once I saw how the hand is captured and some fiddling it all works fine now. Thank you again.

That was a random spring in the photo that came off of something else, not part of the S&W.
