As I understand it, the Bushman triggers are designed specifically for the 995, and the 4095 rifles. He had one for the JHP 45, but I am unsure if it is still available.
I have not disassembled my C9 down to the trigger to compare it to the 995, but I am assuming they are different in some subtle way.
Bushman, are you out there? Care to weigh in on this one? http://bushmanparts.com/osc/index.php
Sorry for the delay folks. I didn't ask Hi-Point and just spoke to them today. I forgot. I will call Bushman in the morning and see what the verdict is from that end. Wrote a post-it note for myself even.
