Thanks!
Unit ended up weighing a bit less than the OEM handle. I am happy with this result considering how much bigger the handle is, and also using a steel tang. The lighting makes a big difference for how dark the handle looks. Both examples are blasted, and oiled.
Just wanted to update you all. Was still tweaking the design for the detent... Hoping for you all to be pleasantly surprised at what I was able to accomplish with my design. I spent a bit more $$ on R&D as I had a specific vision for what I wanted out of it.. for a smaller company it was a big leap, I believe it will be worth it.
Photos will be added this week most likely, in addition to me being able to start taking orders (hopefully).
I used their supplied spring. I don't know if it is a different weight. Like maybe they calculated the weight of the pad into the spring rate? I'd guess either would work fine once set correctly.
