Pls help me decide...9mm or .40

**FF750** · 05-11-09, 15:48

I've always wanted a Walther P99 and I'm planning on having my local FFL order one. I've pretty much decided I want an all-black AS trigger model but I'm going back and forth on what caliber to get it in.

I already have a Springfield XDm in .40 that I really like and have a healthy stash of .40 tucked away. Together with the theoretically better stopping power of .40 those are good reasons to get it in that caliber.

But there's also the appeal of getting a new caliber (this will be my first 9) and the benefit of more rounds per clip (14 versus 12). Not to mention that a P99 in 9mm just sounds right dontyathink (that's not really a serious reason but it's an amusing one lol)?

Price is pretty much the same for either.

So what do you guys think?

Oh, and please no flaming saying I should get a Glock, 1911, M&P, or somebody else's other favorite model - I know there are other guns that are just as good or better out there - this is just a pistol I've always liked.

I don't think the idea of a differential in "stopping power" (or even it's arguable existance in service handgun calibers) is going to gain a lot of traction here.

The P99 9mm has a standard capacity magazine of 15 rounds (not 14).

I would personally get the 9mm.

There's little to no difference in between the premium offerings of 9mm and 40SW.

There's potentially substantial difference in costs, esp over the lifetime of the gun.

Magazine capacity is not a consideration for me above 10-12 rounds.

I'd choose neither the Walther nor the SAI, for reasons you can review via the search button. First choice remains a G17 or a G19 in a 9mm for anything important.

I agree! The clips are easier to find and buy!

You're killing me.

The best reason for me in choosing a pistol caliber is cost of shooting as I'm not an LEO or military guy. So that being said I would choose 9mm while not a whole lot cheaper right now it is still cheaper, and over the course of your pistols lifetime the savings will start to add up.

How quickly and how accurately you can shoot your pistol is of far more importance than what caliber it is.

PS - clips, FFS

Okay thank you for the input. Yes, I know I made a mistake putting clip instead of magazine. I appreciate the correction but I didn't feel like it was necessary to make me sound like a total idiot for a common error. Some responses were more diplomatic than others about it and to those that responded with helpful advice (and not just took the liberty to poke fun) I thank you very much. To the others, sorry for being such a noob, I'll be sure to keep out of your way then next time since you guys are obviously so much more HSLD than I am.
