I just got my P38/P1 in the mail. Its a postwar with the alloy frame. I picked on with the lug and extended slide serrations. I hope I made the right choice. From what I read online it seems that lug was put there to strengthen, or create a stronger wear point. I know I should have pics post but the only digital camera I have is a phone and the pic really sucks, maybe when my roommate wakes up I will use his. Anyone have any experience with these. I thought they were about the size of a CZ82 but its actual physical demensions match my 45acp XD with the longer barrel. It is however lighther than both the cz and XD
