Ok. I finished the job with some success.
I did adjust the Safety Spring Tension, and now the mushy feel is completely gone. The Safety Lever now has a very positive and audible click. The difference is significant, and much better. the process was relatively easy for me.
I documented the process for anyone who is curious. DISCLAIMER: I am not a professional gunsmith. My notes and pics on this post are for education purposes only. I do not encourage anyone to do the same.
Now that we have that out of the way:
- I ensured gun was unloaded
- I separated the Slide from the Frame - set aside Takedown Pin
- I separated the Trigger Assembly from the Frame:
- When doing the above, the Takedown Pin lock will come lose. I removed it and set it aside.
- Then I separated the Safety Lever and Spring from the Trigger Assembly.
The Safety Lever simply pulls right out. The Spring is easily removed after that.
The Spring is easy to lose. It may even pop out by itself:
- I very slightly
bent the encircled portions of the Safety Spring, pictured above, so that it ended up looking like the picture on the right.
- I then Reinstalled the Lever and Spring as noted below:
- I then reassembled the whole firearm.
The end result for me was a much more positive and snappy clicking of the Safety Lever. It does not take much change to the Spring to change the feel of the Lever.
With that said, I have some additional notes, pertaining to the LC9S on a Kydex holster:
Changing the spring tension on the Lever did not change my Kydex holster's ability to disengage the Safety on certain situations/angles. The new spring tension made it more difficult, but it was still possible for the Safety to disengage.
I then took my Kydex holster and with a hairdryer remolded the space for the Safety Lever so that it was "less square" and more rounded. Between adjusting the Spring Tension and remolding the Kydex this has apparently cured my Safety-disengaging problem.
Below is a pic of what I did to the Kydex holster. The Red Circle shows the space for the Slide Release Lever, which is shaped snuggly to that Lever.
The Safety Lever provision was also very snug before. I reshaped it so that its more contoured and doesn't have an angle to allow the Safety to get engaged:
Hope this is informative. Thank you to Boom for the Tips!
