The USPc almost cocks itself.
Flip the safety on, point gun in safe difection, pull trigger.
The gun is now in half-cock.
To be honest, if the chamber is loaded, and you decock it, the gun is in half-cock.
Safety still on, pull trigger a little bit to the rear, and thumb cock the gun, it's really easy with the rubber tipped-hammer.
Anyone who disses the USPc series gun has never kept it long enough for the trigger to break in.
The USPc wasn't designed, it was engineered.
Also, you can carry it cocked and locked, so you wouldn't need to thumb cock the hammer for a SA first shot, if that's your thing.
And as for the safety engaging while firing, somebody doesn't know what they're talking about.
My USP compact .45 has never malfunctioned, not even once, is the only auto I own with a 100% reliability record (Almost 10,000 rounds through her!), and its also the most accurate auto I own.
The only thing my USPc could use is night sights, but that's available aftermarket.
