[QUOTE="_CY_, post: 979937, member: 7629"] along with polishing and changing out springs... sear angles can also be changed to reduce trigger weight. the most radical trigger weight changes are done with sear angles. usually changing sear angles should only be done by a competent gunsmith. there's negative, neutral and positive sear angles. only positive sear angles are acceptable. to find out what you have ... with pistol unloaded... carefully pull trigger while watching hammer.... your hammer should move very slightly backwards before releasing with a positive sear. this means spring tension will jam sear together at rest. vs a negative sear will move hammer forward creating a very dangerous condition. do you have a trigger scale? if so what's the pull weight? do a slam fire test.... with NO rounds in pistol... making sure your pistol is not loaded. cock... then slam pistol hard against a solid non marring surface at angles as if pistol was dropped. naturally don't slam pistol hard enough to hurt it... what you are doing is replicating forces if you dropped it. trigger sear if done safely will not discharge .... even if slammed HARD! (positive sear angles will jam together harder if bumped) if your trigger releases after a hard slam... STOP... put that gun away and take it to a gunsmith. [/QUOTE]
