The INSP were having unacceptable feeding, ejecting, and non-firing problems in their new Glock 22 and 23 models. I believe they even had a couple of structural gun failures with factory ammo but I may have that mixed up with another instance. I heard Glock was wanting to refurbish/fix the current guns claiming its a "bad batch" while INSP wants to switch to the equivalent 9mm models. Last I heard they were at an impasse but as I have no direct contact with either party and rely on what I hear through the grapevine the situation could be resolved by now.
