Which P99? 40S&W or 9mm

I am pretty convinced I'm going to buy a P99, but I'm not sure which caliber. It will probably be used for home defense. So, what are your thoughts on the pros and cons of each?

Thanks
 
I had the same dilemma, and ended up buying one of each. :D

If 16-round magazines are an option for you, it really boils down to 10 rounds of .40 Auto or 16 rounds of 9mm. If I had 10-round magazines for both, I'd go with a .40 Auto.
 
Which P99? 40S&W or 9mm

It will probably be used for home defense.

If this is the primary use, I would go for the .40S&W with the best self defense ammo that you find your gun shoots the best.

BTW, I would take a hard long look at the Federal 165gr. EFMJ round for the .40. It expands better than some HP's but feeds 100% like ball! :eek:

Otherwise, I mirror what lunde has already stated. :D
 
And now a word from the opposition. :D

Based on everythig that I've read, there's next to nothing you can stop with a .45, or .40 that you can't stop with a 9mm. Any stories you hear about the 9mm failing to stop are usually because of bad placement. Substitute that same scenario with any larger caliber, and the results would be the same. It's rarely the round itself that is to blame. Remember a hit with a .32 is more effective than a miss with a 50AE. Although the point about clip capacity is good, I don't feel it's the defining factor.

For an absolutely lethal round, with more variety than any other caliber, universal availability of ammo (40 SW can sometimes be hard to find), and affordability for practice (bulk 9mm can be had as low as $5/box of 50), it's the way to go.

Visit this website to make a more informed decision. Make a point of reading up on the 'advocacy' sections for both 9 and 40.

This page in particular sums up the choices well. The section on location, location, location, is of particular merit.

look for the proof marks

All the P99 in 9mm are the real deal,made in Germany.S&W made 3,000 slides in .40sw to help accomodate the demand for this pistol and caliber.The S&W slides are notorious for jams and FTF.Search for this topic in previous posts.The proof marks are on the right rear corner of the slide and are represented by a eagle over a circled N.The slides made by S&W aren't worth the price of the pistol and look twice before you buy.I have the Military .40sw with the marks and am very satisfied with the quality.Placement is everything shoot regular and often and place them where you need them.SAFE-SHOOTING!
 
I just purchased my first Walther today. I chose a P99 OD military version in 9mm with the traditional DA/SA trigger configuration. I may get a .40 auto in the future; I tried the QA trigger and liked it very much.
 
They say to buy the largest caliber you can shoot comfortably.

And "They Say" is the universal expert on all things. :D

Seriously, all other things being equal, there is precious little evidence that anything matters except raw caliber. I forget where I saw it, but someone (Chuck Taylor?) said that, in his review of shooting records at his local PD, .45 had a 100% success rate in stopping BGs, as long as they were hit in center of mass.

as long as they were hit in center of mass

My point exactly. PDM, I don't know where you heard this, but everything that I have read at firearmstatistical, Calibers, and elsewhere, points to shot placement as the number one defining criteria. The human anatomy places vital organs 2" beneath the surface. A miss is a miss, and a hit in COM with a .380 will be just as leathal as a .45, however if anyone has other information, I'm always ready to change my view, in the light of new evidence.
