I've got a fullsize and a compact. The full size has 4ish bricks of bulk ammo through it, mostly suppressed. It's as reliable as any other quality .22 pistol I've owned. More reliable than the other high capacity .22s I've got, the Keltec P17 and Sig P322. The compact will probably be the same way, but I've only put 250 rounds through it at this point, all unsuppressed.
