The DUTY model (first model P07 had a curved trigger.
Mine doesn't bite me a bit (P07 DUTY .40 S&W). For some reason the P09 (not stamped DUTY on the slide because it's the newer version of the plastic framed Omega pistols) in .40 S&W would work my finger over pretty good after a couple/three magazines.
I ordered one of the original triggers for the DUTY model and replaced the straighter double/triple bend version trigger in that P09 and no more trigger finger irritation/pain.
The only thing I had to do was take my pocket knife and scrape the inside of the plastic trigger guard near the rear just before it meets the frame/grip. The DUTY trigger must be a little longer and the tip would scrape/bind as it moved to the rear. Only a small amount of plastic has to be removed to allow clearance.
This is my other .40 S&W P07 DUTY, so you can see what the trigger looks like.
