I've always wanted a Ruger 22/45
Sounds like a good enough reason to me to get one.
You're mission, should you choose to accept it, is to convince me that I should go for a revolver of some sort instead.
First question I'd have is whether you know if you'd enjoy shooting a revolver or not. Any trigger time with one? Maybe you'd hate it, in which case, the point is moot.
I have a 10-shot 4" S&W 617 and a 1951 6" S&W K-22. I've enjoyed informal target shooting, and both guns are very accurate. Most of the time, I shoot them double action, but the single action triggers on both are superlative Over time, though, I started to develop an interest in trying some formal bullseye shooting, so even though I love revolvers, I bought a Ruger MkIII. So, after very minimal trigger time with the Ruger, here are my relative Pros/Cons:
Ruger:
Pros:
- Affordable. $325 + tax. A new 617 will likely cost you twice that
- Inherently accurate. Very first time out, with
zero trigger time with it,
no adjustments of the sights, and
no experimentation with ammo, I shot a 1-handed 272/300 on an NRA 20-yard slow fire target.
- I didn't have to shoot DA or reach to cock the trigger (and adjusting my grip)
- Lots of aftermarket parts available, so the action can be tuned relatively easily. If you're mechanically inclined, you can likely do it yourself. Lots of aftermarket grips available, too.
Cons:
- A bit sensitive to the ammo I was using. I was using CCI standard velocity, and had a number of jams. Maybe that'll get better with use, or when I find it's preferred ammo.
- Assembly/disassembly is a PITA.
- Compared to my revolver, it actually takes
more time to send a box of ammo downrange; it may be quicker to slam a mag home, but the mags to have to be loaded, and that takes time.
- brass cleanup. It gets scattered, and if you're not gonna leave it lying around, you'll have to pick it up.
S&W Revolver:
Pros:
- Revolvers are just flat-out cool, and not many can shoot them well.
- inherently accurate guns
- can shoot in double or single action
- There's a certain zen to the double action trigger.
- The SA triggers are terrific right from the factory
- The 617 is a k-frame, so it would make an excellent "understudy" to k- and L-frame centerfire revolvers.
- much less ammo-sensitive
- brass cleanup is much easier
- lots of aftermarket grips available.
- will probably hold their value well, especially if you buy an older K-22/M17.
Cons:
- Some people hate shooting double action, and if you hate shooting double action, you'll have to cock the hammer every shot.
- If you shoot in formal bullseye, you'll likely have to cock the hammer every shot
- If you want to improve the trigger, VQ doesn't make drop-in kits - you'll need a gunsmith.
- The grip angle is pretty slack compared to the 22/45 & 1911. If you're already used to the grip angle of, say a 1911, the grip angle of a revolver may feel very odd. Maybe not a big deal, but it might be for some people.
