Had a slight problem today at the range and am looking for advice. The slide on my Thunder .380 stuck when trying to chamber the first round in my magazine on 2 separate occasions. I had to drop the mag and clear the gun, then start over. I WAS using the CHEAP ammo from Wally-World (Tul-Ammo, I believe...), so I'm wondering if that was the issue. It only happened twice, and both times, only when chambering the first round in a fully loaded mag. It worked great on all the other loads. The gun was very clean and well oiled on the first failure, and had only been through about 21 rounds with the second failure. Anyone else have this issue? Just the fault of the cheap ammo?
