Armscor 10mm in Glock 20?
Bought two boxes of Armscor USA 10mm ammo today (180gr FMJ). Was cheaper than other ammo I've bought in this caliber recently (approx $15 per box cheaper) and it was what was on the shelf. There's a sticker on the box that states "Not for use in unsupported chambers". Anyone used/had issues with this ammo in their glock 20/29?
