I installed an ALG ACT trigger with the reduced power hammer spring included with the trigger, in my PSA AR-9 setup. I’ve only run 100 rounds with the new trigger, and it ran and felt great. Then I read in a few places that reduced power hammer springs shouldn’t be used in blowback AR-9s because the hammer spring tension helps hold the bolt into battery. I am running an 8 oz. buffer for a combined bolt+buffer weight of 23 oz., along with an xp buffer spring.

Has anybody here had issues with reduced power hammer springs in similar setups? What are the risks of using the reduced power spring?
