...As in Gray Guns PELT2 trigger for the Sig post upgraded P320.
It took about 20 minutes to install. It could have been much faster if I would have watched this video...

I was half way there (with the tool-less method in the video) when I gave up in fear of bending the spring. Actually very simple.
The flat trigger feels great, very smooth, my finger indexes easily, and lighter than the stock post upgrade trigger (sorry, no pull gauge).

Nice!! That's on my short list of mods to my P320RX. Now that I'm thinking about it, I just realized I've had it since last summer and haven't even fired more than a mag through it yet. Ugh....
