Hiya romex2121and thx for your thread, being 6 am glad I found something productive to do.
FYI the search function here works much like a google search and the google search will often find old threads buried weeks,months back in this very forum. Just saying. My guess is the factory gun is a 8 pound pull of the D/A and 5 for S/A. And didn't quite notice what wants you wanted in the first place related to the answer. i.e.. wanting lighter or heavier than factory settings. Range,competition,or HD/EDC use. Cheers .be well.
