Last week I put in a NY-1 trigger spring and the pull was really hard. Today I put in Ghost 3.5 connector and the trigger is lighter and pretty nice actually. However when I rack the slight, it is really hard. Its right at the beginning just about an 1/8th of an inch back it feels like its catching something. It did not do this with just the NY-1 trigger and stock connector. Is it the connector hitting the curved part under the slide or is this normal? Would a good polish fix this? Thanks for any help.
