I have noticed this oddity on my Gen 2 G17 . It is a raised piece on the forward portion of the left side of the trigger guard. It is textured like the grip is textured. Is this normal because I have never noticed it . I see it on other G17's on google.com but mine is really pronounced. Is this the area of the mold where the plastic is injected or poured ? It has a prefix of AGA which shows it made in 1992 .
