fx impact trigger blade

I see looks like it would be nice just was wondering if it was a aftermarket part you can purchase

If you Google trigger shoes it comes up with a variety of them you can buy. You just have to be able to mount it to the round post accordingly. 

Though I haven't tried it yet, I like the concept of the BB on the trigger bar, as you always have the same placement on the finger and can know immediately if the hold and pressure is different. This BB can easily be made for the Impact, but the "odd" feeling is something that you would have to get used to, as it is way different from a conventional trigger shoe.
