Wow, this is the first time I have ever seen a glock fail to feed properly.
Guy was using HSM 180 grain ammo. It failed to go into battery 3 times.
I let the guy shoot my Dan wesson with the ammo and it shot 8 rounds just fine. I told him that my 1911 can be finicky and will only shoot good ammo usually. He fired my gun after I had put 50 rounds of lead rounds through it.
He said it was a brand new gun and that was the first he has ever fired it.
I cant imagine a glock needs a break in period?
