Which Trigger Plunger Spring?

[dukeguy]

Need a little direction. My Henning trigger in my Witness Match 9mm has started to bind up, making it sticky to pull and even stickier to reset. I've read up on a couple of threads here and it seems the trigger plunger is the issue. I have shortened the existing spring by cutting off one loop and it seems to have cured the problem. (I'm open to any other advice!)

Now I would like to replace the trigger plunger spring. Henning has 4 springs listed - 19#, 20#, 21# 22#. Are they different lengths, or just different weight or resistance? How do I know which one I should choose? They are all listed for light loads, which is what I shoot with this gun.

Thanks in advance for any help you can give!

I usually use the #20 in my single action pistols.For the DA/SA pistols you may need to use a #21 or #22 due to the increased trigger travel needed during the DA pull.
