Saw some YT videos on the G44 being tested and demoed in the Glock factory. They spent years making it ultimately reliable with all types of .22 ammo, including limiting it to a single stack 10 rounder.
Sounds like it will only fail due to ammo quality rather than anything gun related. If you’re in the market for a new and reliable .22 and already own a G19 or similar, then it’s a no brainer!
