Need some advice. Purchased a PPS 9mm. I felt I did my due diligence researching the weapon as well actually firing it many times at the range. Unfortunately, when I made my purchase, (purchased online) I was not aware of the "H" vs "S" disconnector variation. As you can guess I have the H disconnector weapon. My question is this, living in Miami, Fl. the gunsmith that I contacted to switch the disconnector tells me that he will not do it because the part is riveted to the gun and as such, he feels changing the part out will make the gun likely to misfire. I purchased the regular disconnector from Smith and Wesson but have no one to make the change. Is the gunsmith here correct in his assertion? If not any suggestions as to whom I can contact to make this switch? Thank you for any help.
