I picked up a Sig M 17 comm the 2 nd day they were out , made a special trip that day to get it . I have maybe 450 to 500 rds no problems but sometimes it stays out of Batt if you pull the slide back for like a press check thing ,it seems a little tight yet . Went to the gun shop Sat and they still had some Sig M 17 Comm in the big show case 949 . I was surprised to see one in the case .
