I inherited a gun collection from my brother's estate. He had several brand new high quality rifles and handguns. I've taken most to a federal firearm licensed dealer to help market them.
I am going to keep at least one. I am on the fence about keeping a brand new Glock 19 9mm or a very nice almost new Walther PPK .380 cal.
I already have two CCW weapons in .38cal and 9mm. I'm a lifelong James Bond fan and lean a bit towards the little Walther.
Which would you keep?
I mean, it sounds like you just want a range toy. You don't really NEED another gun. So, in that case, I'd keep the Walther. Glock 19s are fine firearms, I own one, shoot it regularly and have been nothing but pleased with the pistol's performance.
However, they're not neat, or sexy, or cool. They're just a functional, reliable firearm. When it comes to actual, practical use, the Glock is hands down a superior pistol, but it sounds like that's really not an issue for you.
Since the PPK is cooler, I'd probably keep it.
That said, the PPK is probably worth more (seriously, the prices Walther asks and gets for a 90 year old simple blowback gun are ABSURD), so if you need the money there's that.
