TM PX4 trigger issue

[Jammanic]

Hi guys after changing the lower of my TM PX4 the dual action of the trigger isnt working (shown in video)

It only needs a tiny bit of pressure to set it again and Ive lubed/given it a bit of a kicking and cant get it to correct itself.

The pistol works fine if I cock the first shot like a cowboy it'll run through the mag with no problems but Id rather have it functioning 100% again.

Cheers!

What lower did you put on it? Not a PX4 expert but it looks like the sear isn’t engaging with the trigger bar correctly

Ok cool I’ll have a read into that issue then as I’m not very experienced with GBBs (which is why I ripped this apart) ?
