Which Witness trigger return spring?

[Tampa-XD45]

I'm installing a Henning flat trigger in my Witness Elite Limited 9mm and the trigger return spring decided to take a journey somewhere into the depths of my workshop.

Which one should I buy to replace it?

If you're installing the Henning, it has a totally different return spring.  If your stock one went flying, you should still be in luck.

I believe Henning sells a multiple spring pack.

 

If you need the stock return spring, get the reduced power.

Henning trigger, as mentioned, does not use the stock TF spring.

Neither of those mention by the OP are correct. 

 

Use this:

I understand the Henning uses a different spring that's included in the flat trigger kit.  I just want a factory spring to keep with the factory trigger.  

I'll buy the one from Ben Stoeger in case I don't like the Henning trigger (unlikely) or I sell the gun (also unlikely) and want to include the original trigger.
