No, not that I know of ...but its because there are too many variables...
Some mfg's websites -- like Sig Sauer....will tell you what the spec on the trigger pulls are...../ but while a gun you order may be close to the spec in the catalog...you'll have to measure each gun / and I find it varies quite a bit + or minus 1/4 to 3/4 of a pound often....
A lot of us ....on higher end guns....will specify the trigger pull we want on a gun when we order it. Some mfg's, like Freedom Arms revolvers... will say their trigger pulls are typically 4.25 lbs...but if you want to pay for a honed action they will take it down to 3.0 lbs...or whatever you want in between when you order the gun.
Sometimes a good cleaning / changing the lubes or grease on a stock gun ...and/or changing the main spring, hammer strut spring on a gun can change the trigger pull as much as 1/2 lb...plus or minus depending on what you want....
On older guns...even very collectable models of S&W revolvers or Colt revolvers....I find trigger pulls both double and single action are all over the board...
