We had them a few years before I started so I checked with the guys that were responsible for the acquisition then. We carried the 1076 model and had the trigger and decocker issues. Like the FBI, some of the officers had issues with the recoil and properly handling the gun. So when the 40 cals came out we traded for them.
Thanks. Was just curious ... Felt-recoil and qual-related issues I guess I can understand. A lot depends on what 10mm ammo was chosen for duty use.
Even back in the day, before the 10mm's resurgence in the 2000s and the proliferation of so-called 'boutique' ammo-makers, not
all 10mm ammo was watered-down to 40-level. You could still find mid- to upper mid-range stuff. Corbon's 10mm ammo was pretty hot, and the old ProLoad outfit offered 180gn Gold Dot ammo @1200+fps. Hornady had their 180gn XTP-HP @ 1180fps (which, thankfully, was recently 'upgraded' to 1275fps - just FYI

).
KSP issued the 1076 as their official duty gun for longer than any other agency I'm aware of, including the FBI (although I knew a few very senior agents in my area who were still carrying 1076s in the early 2000s). KSP's 1076 had undergone the factory recall work.
KSP also issued different makes/brands of 10mm ammo over the years. As I recall, they once issued 180gn JHPs, then at some point switched to a 155gn Gold Dot HP @ something like 1375fps.
In a conversation I had with the guy at Georgia Arms ammo, he said he used to produce that very load for KSP. Not 'reloads,' but fresh ammo using new cases. He used 10mm nickel brass that was head-stamped 'KSP.' He still had a bunch left over from a big run he did, so I bought a case of it and carried and shot it in my 1006. 'KSP'-headstamped and super accurate stuff too.
