If someone has a MA compliant trigger return spring (the heavier one) they have removed and would like sell, please let me know. I would like a slightly "firmer" trigger pull for my carry gun. I already put in the Apex TRS and sear spring, and it is slightly heavier than stock, but not quite where I'd like it. I gather I can't get one direct from S&W because the part number is not generally known or listed on their parts .PDF pages, and even if it were; trigger return springs are restricted/armorer only parts. LMK what you have to offer. THX!!
