I'm always wary of any handgun retailing under $400. Below that price point, something has to give in terms of quality. The P95 is a notable exception.
I've always wondered why you don't see many cops carrying Rugers or them being used by any of the number of Military's we arm. The are inexpensive, durable, reliable and proven.
You'll see them among a great many private security officers. One reason is because they're inexpensive. The other is that they're being deployed with people who don't take care of them.
I don't know how aggressively Ruger has pursued the law-enforcement market, but I
have seen them on the hips of a few officers (mostly in rural areas) over the years. They do take abuse and neglect with grace.
In the 1990's, I was given a well-worn KP90 in return for some services. I didn't shoot it much, but it seemed reasonably accurate. Its greatest virtue was that it was the only automatic that fed my reloads (tailored to a revolver at the time). In fact, it fed just about everything.
At this point, to be taken seriously in competition shooting, you had to have a big, shiny .45. Usually, it was a Colt that had been through all Nine Circles of Gunsmithing Hades ("getting the slide tightened to the frame increases accuracy!"). Often, said gun would have a scope and some sort of goofy counterweight mounted on it. If it wasn't a Colt, it was a Randall or an AMT. If the trigger pull wasn't under three pounds, you weren't a real man.
The whole point was that it had to be the Big Expensive Coolest Thing Ever. The KP90 was the antithesis to that whole idea. It had a mushy trigger, it didn't have geegaws stuck to it, and it wasn't a brand gun writers gushed poetic over. Good lord, it was a DOUBLE ACTION! Everybody knows you can't shoot
those well!
But it did one thing none of those guns ever could: feed a magazine worth of ammo without jamming. As such, I kept it in my range bag should someone's fancy bushing or custom sear crack, and it ended up being used quite often.
