I saw those, too. Yhey need to make more! That's why I posted - in case someone knew another supplier of themThis is the only skeletonized trigger that I know of. It looks like they sold all of them, but try sending the seller a message. Maybe there are more in production?

As far as the warranty, I don't think it voids it but maybe someone else can clarify that. The above link has a Youtube link for the trigger removal-

twowheels, I need to take mine back apart and do some polishing. I'm not particularly happy with the trigger on either my P238 or P938. I little lighter and smoother would be nice. I agree that you need to wack that trigger pivot pin pretty hard to get it started. I soaked mine over night in some Kroil oil and it freed up easier than what I had anticipated after reading all the horror stories.I also installed a tillamook precision trigger in my 938. While at it, I also did some polishing and spring tuning to markedly improve the horrible stock trigger. It's not particularly hard for someone who is handy tearing down firearms but there are a few issues that require some acumen. First, the mag release on my gun is fiddly and finicky to get out and put back in. Second, you need the right tools and confidence to remove the trigger pin. You can't be afraid to hit it hard or you will never get it out. Third, if you dig into the guts, reinstalling the sear and sear spring can be a little tricky. All in all, its more complex that than a glock but easier than a CZ.
