Hello all, While cleaning my G20 the other day, I noticed the what initially looked like cracks in the frame around the trigger hole. In talking to Glock USA, their opinion is that they are moulding seems. These so-called seems are perfectly straight, so I understand that they may very well be there from the manufacturing process (and that i just never noticed them before), but I would like to be sure. Can anyone look at the pictures and tell me if these are anything i need to worry about? Thanks for your help!
