    Ok .... This might be a really dumb question but I'm new to shooting.

    I have a new G17 that I have put about 200 rounds through without any problem. I went to the range today with my buddy who has a XDm 9mm. We both started shooting 115g 9mm and everything was ok. In my 2nd clip my 17 started to jam really bad. It wouldn't ejecting the shells.

    I didn't know what the problem was so I switched to a 124grain 9mm and it started to shoot fine.

    I was really confused why my G17 would only shoot 124g ammo.

    Then my buddy started to shoot his XDm without any problems, but in his 3rd clip his started to jam really bad also. He has a new XDm 9mm that he has gone through at least 1K rounds. We weren't using the same ammo either.

    It was very hot today. The heat index in Raleigh/Durham NC was over 110 degrees.

    Could the heat and humidity really cause our guns to jam like that? Is that why the 124g ammo worked and the 115g didnt'?

    I would think the problem was you were using clips when you guys should of been using magazines. I'm just messing with you. :supergrin:

    It could of just been some bad ammo.

    don't think it was either weapon, could the heat/humidity have had an effect on your ammo?

    my last range outing was on a very hot day, ammo left on the bench became almost too hot to handle, that and one of the hotest days I've seen in a while shortened that range outing to just over an hour

    Don't know if an extra 10 or 15 degrees really makes that much of a difference but both guns I shot yesterday (AR and G19) were absolutely and completely bone dry when I broke them down for cleaning last night.

    If anything I would say the heat would make the powder burn a little faster which should help with ejection.(more velocity)

    The only thing I could think of is maybe a different grip cause of sweaty hands and trying not to drop guns

    Was the 115gr ammo Federal Champion?
    If so... shoot something a little "hotter", that stuff is seriously under powered.

    Unless they've been loaded using a powder like WST, which is inverse temp sensitive & loses velocity in high heat.

    With all the ammo companies cutting corners, ramping up production & throwing QC out the window, it seems like the only way to get consistent ammunition is to handload. I'm so glad I don't have to deal will that mess.

    Sounds to me like dry, dirty guns.

    I live and shoot in a very hot part of the country and have never had malfunctions due to temps. I've carried weapons and operated in hotter temps than here and the only probs came from dirt in the guns and the oil "burning off" faster than normal.

    Sincerely doubt heat was the issue.

    I've shot thousands of rounds of Federal Champion 115g 9mm from Wally World. Never a hiccup in my Glock. The Jimenez 9mm I had for a month didn't like them, but the Glock eats them up all day long no problem. I've heard many people dog Federal on here... can't beat $12 right now for 9mm ammo unless you go Tul-Ammo steel. That stuff is like $9. Anyhow, Federal works just fine for me and it was 109 degrees here all week last week.

    Thank you for the response but this is not the issue.

    We both just cleaned our guns and oiled them down the last time we shot a couple of weeks ago. So the guns weren't' dry or dirty.

    Thanks everybody for your thoughts.

    I just cleaned the gun up and I will go out again this week and try again.

    That might be true for a 3rd gen. But the 4th gens have problems with underpowered ammo

    I'm guessing this means ... "Winchester White Box"

    This is actually the ammo we were shooting. Have other people with Gen 4 (9mm) glocks had this problem with WWB?

    WWB is OK Ammo for the range but I've had many problems with it in All my Glocks. I get light strikes even with a Jager Striker.. Also feeding problems etc..
