P239 SRT upgrade
Might grab another 239. This would be a plane Jane model. I know SRT kits are now hens teeth. Is there another option besides a custom gunsmith job?




A 9mm in MY Hand is better than a 45 at home.

Any classic P series SRT kit will work in your P239. They all share the same sear and safety lever. Purchase the 226 SRT Kit from TGS and you will be good to go.

The kit for the P239 included a trigger bar spring. Other than that the sear and lever are standard P series parts. Any SRT kit will work but you may have to grind down the end of your trigger bar spring where it hooks into the trigger bar. An easy enough fix if you have a dremel or even some wire cutters.

I *MIGHT* have a 239 kit in my parts bin but as others said, there's a new trigger bar spring included and that's about it. The sear and safety lever are the same as the classic line.

I'm fairly certain that the trigger bar spring in the P239 srt kit is a P225 A1 trigger bar spring.

P226 srt kit plus
P225 A1 trigger bar spring.
