My PK380
My wife has arthritis, and at Cabella's in Hamburg, PA she did not like how hard the slide was to operating on the Walther PPS and the Ruger LCP .380, and I didn't like either so well that I bought myself one anyway. However, when she got my newly-purchased Walther PK380 in her hands, she approved. The recoil isn't bad; she doesn't like the recoil from my 9mm single-column SIG or her Taurus 9mm (similar to the military's M9 Beretta).
But, she likes my PK380.
No external Slide lock/release. But, I reach into the breach with the slide drawn back (it isn't a hand-slammer spring, remember) and flick the little lever up to lock the gun open. So, that turned out not to be a deal-breaker. It locks open on an empty clip after its last shot. To release, drop the mag (or I suppose I could depress the magazine follower through the ejection port) and pull back a little on the slide and it closes.
She's more accurate with the PK 380 than either of our 9's or any of the other 9's in the family, all of which she's tried.
The PK 380 is mine, my choice because my P-22 is the most accurate .22 I've ever owned. I'm certain from a machine rest there are other equally accurate .22's I've handled. But, my P22
fits my hand. That makes it the one for me, because it got me results. I bought the PK 380 after checking how well it fits my hands, and now that I've had it to the range twice, I love the accuracy it gives me.
If someone built a 9mm on a frame that fit my hand this well, I'd consider it. A harder-hitting round would be good. Until that time, my PK 380 has proven to be more accurate
for me.
I'm pretty sure that you're mileage will vary. I will say that if you like the way the P-22 feels, and more importantly shoots, in your hands, you should try the PK 380.
I sure love mine.
