Had my SA mil-spec at the range today for the second time. 1st trip fired 100 rounds with no issues. Today an issue came up. During cycling the slide would stop about 1/4 from full battery. Would not do it each time, but when it did it took some work to get it moving again. Used a variety of ammo with the same results. Only change between trips was a new trigger (longer shoe). Saw on another site that too much pressue on the middle spring/disconnecter could cause this. Could a slightly longer bow on the new trigger be the problem? Need to hear from the 1911 gurus out there.
