Way to go powerman! I just got an hkusp9compact...put meprolight night sights on it,but fubared the rear,so ive got another coming...using the standard rear for now...put the reduced hammer spring in it,but tell me how hard is the extended mag drop to put in? The HK runs awesome...just cant get used to the dead on hold where you cover up the target...instead of the 6 oclock hold....getting used to that
congrats on a fine piece
