Hi Dan and welcome. This is an error. Smith and Wesson explicitly say "NO" on their website: --- smith-wesson.com/product/mp9-full-ca-compliant ------------- Trigger pull is between 4.5 and 5.5 lbs. Cheers, stay safe and enjoy!

typo its a 5-6 lb trigger pull The MA compliant gun has a 10lb trigger not the CA compliant gun The 10 lb trigger is model # 13007 budsgunshop.com/product_info.php/products_id/118839/smith+%26+wesson+mp45+m2.0+.45+acp+10+1+4.6+ma

Hi Dan, that is a typo, this gun does not have a 10lb trigger, more like 5 lbs >>> smith-wesson.com/product/mp9-compact-ca-compliant
Stay safe & have a great day!

That is an error, actual trigger pull is 5-6lb
