What are the trigger pull weights on usps?

[navyman8903]

Does any one know what the trigger pull for a usp .45acp da/sa?
And a usp .40 LEM da?

I would like to know as well. From what I've heard, the DA is around 12lbs, the SA is around 4lbs and LEM is around 7lbs.

Remember, there are no absolutes. All will be within a range but all will not be the same. Almost every time I post this someone will come on and say, "But mine has a XXXX pound pull." So, to avoid getting into that, if is within a pound or even two pounds either way, nothing is wrong, it is normal gun to gun variance, it may be that the pistol is cleaner or dirtier than mine or may have been shot more or less than mine. On multiple guns of the same model, if the SA pull was about the same as others I did not do a DA pull on that particular pistol.
When I was keeping track of such things, this is what I measured on a few of mine:
Trigger pulls: SA , then SA and DA revised with Lyman digital TP gauge.

Wow, that's great information, thanks to Big Bore! (I just got an Expert recently and was amazed at how light and crisp the trigger was. Thought maybe some work had been done to it but looks like yours is the same. Yeehaw!)
