If you're referring to within the People's Republic of Kalifornia, then no, under the state assault weapon ban, they have been banned for sale as of 1/1/00. Dumb as it sounds, any semi-auto pistol with a threaded barrel, regardless of capacity, etc., has been a CA assault weapon as of 1/1/00 with all the restrictions and registration requirements thereof.
As I understand it, if one swaps out the threaded barrel with a non-threaded barrel, then AW registration and restrictions do not apply... Stupid, I know, but there it is...
FWIW, Glocks come from the factory with a 5.5# trigger.
If you are referring to the USP's DA pull, that's around 9 - 10 #'s, SA is probably in the 5.5# range, too.
I've read somewhere that there is a match trigger for USP's, maybe something HK can do for a fee. Don't know anything else, other than it's suppose to be lighter, smoother, better...
Fwiw, the USP trigger should smooth out after break-in and maybe even lighten up a bit.
The rep is that they are reliable and accurate. I got one of the rare lemons in .45. Took 5 trips back to get it feeding reliably. Everyone else I've talked to with one, says their's runs 100% reliable. I'm just the 'lucky' one... <g>
It is very accurate. Probably it's best feature on mine. I prefer a good 1911 trigger, followed by the Glock trigger. To me the USP's pull and break feels plastic-like.
