I got my V-day gift today! My DH bought me the Montorgueil GM! I tried it on and it looked a little too big. I was thinking of exchanging it for the PM, but i know the salesperson said they were quickly selling out. Did anyone ever try the GM and PM? I was wondering if the distance between the strap and the bag were the same? Besides the size of the bags, is there any other differences? What would you do?
