Re: Bulged Barrel?
Glocks do not have an "unsupported chamber". In the Glock, the cartridge is not as well supported at the lower rear than with some other guns, and that has reportedly caused problems with some ammunition, both reloads and factory ammo.
But there is no, let me repeat, NO, indication that proper reloads are going to blow up a Glock or any other gun. Of course, reloads that have excessive powder charges or that use defective or excessively worked cases can be a problem in any gun, but the blanket statement that reloads will damage a Glock is simply not true.
As I said before, ALL gun makers advise against use of reloads for the simple reason that they can't and won't assume any liability for their gun if used with ammunition of unknown origin and unknown loadings.
