I have a police trade in G23 with a NY1 trigger installed. I recently swapped in a G22/17 trigger/trigger bar. Yesterday when dry firing the trigger began to feel progressively heavier and eventually felt so heavy I thought something might give if i kept pressing. I stripped the frame to check everything it seemed ok so i reassembled it and began to dry fire again. It seemed to had resolved itself initially but then reverted to an extremely heavy pull. I put the old trigger and trigger bar back in and it seems to be ok now. Was this the result of an out of spec trigger bar or should i be worried about something else?
