You might fit a Walther PP barrel on a PPK to get the extra length.

BTW, I own and carry both the P3AT and the P-11. The P-11 is really just a 7/8 size Glock 19. It’s pretty fat, an inch wide. The P3AT is only 6/10ths wide, IIRC. The P-11 is MUCH easier to shoot accurately, in fact I qualified with it (Possible!) on a multi-stage police course recently. I doubt if I could qualify with the P3AT, which is really a belly gun. The P-11 has 3-Dot sights, and the P3AT has only a rudimentary sight. I will not ever try to aim the P3AT, only point-shoot with it. Make the first shot a low, then walk the other 6 rounds up the target. I ALWAYS carry a spare P3AT mag on my belt (in an old Leatherman multi-tool case modified for it, so everyone thinks it’s just a knife). I never carry loose magazines in pockets, they tend to snag and get full of pocket gnurds.

The LCP does not lock back when empty. It just has a manual lock you can engage.

It’s far more accurate – it stays in the 10 ring at 10 yards. Plus, the slide locks back after the last round. It’s a simple design, similar to a Glock striker, with the only external switches being a slide lock and a mag release.

Granted, you can buy 2 Kel-Tecs for the price of one Kahr, but you get what you pay for.

… or your eyes are old enough that their focus is fixed at distance and you need reading glasses to focus on the the miniscule sights that are milled into the top of the slide, even with luminous sight paint added thereto, so when seconds count, picking up the sights at all is just wishful thinking.

I have this limitation, and laser sights overcome it quite well.

What might be nice is some after-market kit that prevents the slide from going out of battery if the muzzle is pressed against something.

I reload for mine. Even with virgin components I can make a round that equals the “self defense” loads for close to half the price.

And, Jim is correct. The slide does NOT automatically lock back when the last shot is fired. But it does lock back manually, which makes loading it 6+1 quite easy.

A hint: Get a firm grip, then grip it much harder. Center the pad of the trigger finger on the trigger and keep the last joint of the finger well outside the trigger guard.

It’s a handful, but it’s a nice handful.
