When I bought my P30S and right off the bat I disliked the safety lever. The more I shot the gun the more I hated the safety lever. So, I started reading threads in this forum about removing the safety lever, but most of the threads I read suggested that the P30S hammer axle/safety lever is not swappable with the P30 hammer axle. In fact, I found only one guy who said P30S can be converted to P30; I asked him if he actually did it but got no reply.
Then, I decided to try it myself to see if it works or not. I ordered these items:
Option #1
1- P30 V1 AND V3 HAMMER AXLE #209272

2- P30 V3 CONTROL LATCH #234487

Steps:
1- swap the P30S V3 HAMMER AXLE / SAFETY LEVER #227813 with the P30 V1 AND V3 HAMMER AXLE #209272
2- swap the P30S V3 control latch #227812 with the P30 V3 CONTROL LATCH #234487
or (if you want a shorter trigger reset)
Option #2

2- GRAYGUNS Short Reset System for DA/SA and LEM Triggers (models without safety) #SYS-HK-P30-STD

Steps:
1- swap the Firing Pin Block Spring with the GRAYGUNS light one.
2- swap the short pin in the sear/decocker lever with the GRAYGUNS longer one
3- swap the P30S V3 HAMMER AXLE / SAFETY LEVER #227813 with the P30 V1 AND V3 HAMMER AXLE #209272
4- swap the P30S V3 control latch #227812 with the GRAYGUNS one
I did the conversion and here’s the result:
I shot 100 Winchester 115g rounds with zero malfunctions, and I plan to shoot more to test this configuration.

Side Note: Initially, I ground the left side safety lever myself to reduce its size and here’s the result:
but I didn't like my craftsmanship, and I am sure some of you can do better.
I hope that was useful for you
