.40 S&W or 9mm in new Pistol

I have a dilemma. It's been a long time since I've shot a .40 and that was in a Springfield XD. I shoot mainly 9mm in poly framed guns and .45ACP in my 1911's. The pistol I'm looking at is an STI 2011 Tactical with a 4" barrel and full dust cover. I have an option to buy this pistol in 9mm, but it's $50 more than the .40 S&W. The other total garbage is the mag capacity. Standard capacity for 9mm is 17rds. The .40 is 14rd. A spare 2011 mag is $60.

I'm thinking the .40 will save me a lot of headache and $$$ concerning the mag capacity. The 9mm comes with a 10rd mag in restricted states to be legal. What say you in this situation?

Unless you have a real hankering for .40 S&W, I would stay with what you already have, 9mm.

Do you have plans for what niche this gun will fill for you?

The money you save won't reduce your frustration from not hitting where you want if the snap doesn't work for you.

9mm. There is also a thread I put up on the FBI tests with 40 and how hard it is on guns.

buy both and give me the one u don't like...

I like both cartridges and have owned many pistols in both calibers, but I vote 9mm.

This pistol will be my primary SD/carry piece. I currently employ a .45ACP Gov. 1911, CZ P07 9mm and at times a HK P30 9mm. I keep the manual of arms the same on these pistols since the HK has a thumb safety and the CZ is convertible. The STI will weight in at 30 ounces. Here's another kicker. I found another online dealer with a 3" aluminum frame version for $300 LESS than the 4" version. Still in .40 S&W. I am extremely well versed in how 1911's function by design and do all my own machine work on them. There are ways to mitigate the timing of the slide to reduce muzzle rise other than a recoil spring change. This gives me some options. I think it need to rent a .40 S&W pistol. Most of my training I shoot at 25yd and under.

That'd be my dream gun caliber right there.

The amount money they want for those things, I would get the 45 just for resale value. Otherwise get the 40 if for no other reason than the mag capacity here in Kolorado. I also come from the school of equal and opposite reaction. If the 40 is kicking your but on this side of the gun what is it doing to the perp on the otherside.
