Hi.....new member here. I just bought this M40A1 on GB, and haven't received it yet. Just wondering if we can tell by the serial number if it has the new extractor, or not.....? Serial number is 051029 Price was $299 with four 12rd magazines.....that was the starting price, and no other bidders. Thanks....and, I'll be checking this site out in the next few days. Looking forward to shooting this. I've always thought this would be the perfect handgun for the 40sw cartridge......I guess I'll see about that!
