SAAMI doesn't spec a +P .380 load; no publicly traded company can say their gun is rated for "+P" in the absence of a nationally acccepted standard. The Buffalo Bore guys know what they're doing, but you need to understand that when you step outside of national pressure standards, you are on your own!
I was one of the guys who hammered out the .38 Super (and the first "Major 9mm")back in the early days of USPSA...bottom line, we blew up guns. We all came to respect Mr. Pressure.
Regarding the BB .380 — which is, as near as I can tell, the only .380 out there described as "+P." My advice would be use it sparingly. Practice with ball!
RE: Trigger...mine's fine, as has been the trigger pull of all the ones I've shot. Don;t know what the weights are, but they're all pretty smooth. I'm not sure I would want a lighter trigger pull on a pocket pistol!
