357python,
Yes, the Illinois State Police carried the Model 39, the first major department in the U.S. to issue an automatic and was expected to be the off duty gun as well.
The funny, silly thing, about the first issuance is the State Police were saddled with cross-draw flap holsters on the left hip and weren't allowed to have magazine pouches which would have screwed up the lines of the belt with
shoulder strap.
And because they were issued WD40 as I guess a "lubricant" the guns jammed. That gave the aluminum framed Model 39 a bad rep.
As time passed the Illinois State Police also got Winchester, IIRC, to make plus P plus 9 mm rounds.
The most sought after Model 39s are the few made with steel frames.
After my .45 Combat Commander, the Model 39 was my second auto.
I shot at an indoor range run by state police officers. A couple of them
told me about the Browning Hi Power, which then became a lifelong love affair with that gun.
Now, this is for SaxonPig: You must seek out a chrome or nickel plated Hi Power and be sure it has the gold trigger!!!!!!!!
