I picked up the new Gen 5 19 and also the 17 and the frame not being rounded at at the front did not bother me or I did not think about out . I think my 19 and 17 have been flawless . I think I saw some new 19 gen 5 out at a shop that are more round to match the slide .I almost traded but mine have the FBI nights sights and I knew I would loose big time trading. Will they all be like this now . I got my guns the first week they came out .
