COMING SOON – NOT YET AVAILABLE
Got the sear out of my own TP9, and have it modeled in CAD.
First samples are being cut.
Expect that I can make this into a decent 2-stage, despite the strange design. TBD how much of the squishyness of the linkage can be removed. I’m sure it can be made better, but there is a point of diminishing returns versus cost and R&D time.

WooHoo! latest generation of the B&T TP-9 2-stage sear is in, and it isn’t bad at all – for what it is. I was able to get the pull to right at 7lb, with a reasonably crisp 2-stage. First stage is about 5.5lb, with an additional 1.5lb on the second stage. The plastic components, plus the long linkage still leave it feeling a little squishy, so it is not a match trigger, but for a Tactical Pistol it is surprisingly good. More than I expected. I like! I need to run some spring math for the new sear, I might be able to tweek it even better.
I’ll get a few of these into testing with some friends. I’ll also get a few NiB coated (prototypes are just RPS – Rolled Plate Steel). That might help pull a little more.
Tomorrow I’ll go back and re-install the stock sear, ’cause I forgot to measure it, but I know it is heavier with no 2-stage.
I’ll update as we progress.
