The BHSS trigger is more than just a replacement trigger. It is a complete overhaul of the trigger sub assembly system, with an optional but included magazine eject spring, and four different trigger springs which allow the user to choose a lighter, or heavier trigger pull.
I have the #2 spring (second heaviest) installed on mine. I’m getting a 4# 5.2 ounce pull which is very smooth and consistent. For me, with the 9mm extra wide serrated face trigger, it is perfect on my daily carry High Power. I’ll receive a second trigger shortly, the 8.4mm smooth face, and intend to install it with the lightest spring in my ‘81 SilverChrome, my favorite High Power at the range.
I could be mistaken, as I’ve never seen a Garthwaite trigger in person, but I imagine the BHSS Advanced Trigger Sub Assembly will far out perform the Garthwaite or any other “replacement trigger” installed in a standard HP trigger system.
It looks like the BHSS going price is right around $100 with BHVET discounts, $125 without. Compared to the C&S Wide Combat Trigger at $52.50 today, this seems like a bargain for improvements in design and functionality. I actually have the C&S trigger installed on 5 of my High Powers. Although I really liked the C&S trigger, they will likely be replaced as soon as my back ordered serrated triggers arrive, unless I change my mind and prefer the smooth faced trigger!
I ran most of 17 magazines through mine last week. My trigger finger REALLY likes it and my shooting has improved... partly due to the new BHSS Elite Barrel which was also used for the first time at this outing.
Cheers,
