10mm Pistol /ammo information ?

[KK20]

Over the years I accumulated a few glocks in 10mm and they are all not the same and I posted pictures to show differences in the chamber support.

I used to use Lynx bore cleaner which was excellent to get the lead out but sadly cannot get it now.

Plug the muzzle with a cork, and fill the barrel with a mixture of hydrogen peroxide and vinegar, which dissolves lead.

Keep it off the blueing, the mixture will remove it after enough time.
