I ordered this sometime back and by the time I got it-6weeks- and waiting a while, I've decided I'm happy with the standard trigger on my HW50. It fits any HW gun with the Record trigger. Get mine and you don't have to wait for 6 weeks or more. It's still in the pkg, I never opened it. I paid $60 for it and I'll sell it for $60, but I'll cover the shipping and paypal to you, CONUS only. Thanks, Ernie
