    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?

    You should be fine running it in your G20. Usually the "unsupported chambers" specification is meant for 10mm barrels without a ramp, like the Colt Delta Elite 1911 style pistol. Your G20, especially if it's of newer production, has plenty of case support for any factory loading.

    The only 10mm ammo that I know of that was too hot to run in a stock G20 barrel was Swamp Fox's special "aftermarket barrel only" loads.

    Thanks for the information. Just read the same thing on the underwood web page for 10mm.
