The 10mm Auto (10x25mm) is more powerful than the .40 S&W (10x22mm). The .40 came from the 10mm Auto. On average, the .40 carries more muzzle energy than the 9mm (9x19mm).I'm looking to buy another gun within the next month. Im torn between a .40 cal and 10mm. I do not have either one nor have I ever shot either one. I know that the ammo for the 10mm is more expensive than the .40 cal. Which one is more powerful? I have heard some say its the .40 and others say its the 10mm. Heck i have heard some say the 9mm is more powerful than the .40. With so many different opinions how is one to know who to believe? This is why I like INGO, there is a lot of knowledge here. Hopefully there is more knowledge than ignorance. Just kidding.
I shot the my XDm .40 3.8" and compared it to a Tanfoglio 10mm at the range. Honestly, I couldn't tell much difference between them as far as recoil or anything. But the 10mm is definitely the more powerful load, however there is nothing wrong with a .40. If you are going to get a 10milli though, I hear G20 is the way to go.
I believe from the deadly result of the FBI shootout in Miami that prompted the 9mm needed to upgrade into something more powerful and be a man stopper. Then the birth of 10mm was out. But unfortunately, many agents could not handle the recoil of the 10mm. So after a little while, they looked again. I think the result is the .40 S&W or 10mm short.
A Glock 20 is definitely a good 10mm.
But the Glock 29 is also a good 10mm when you need to carry something more compact.
I have both and like them both.
Unfortunately this is a very common misperception and is not really true. The FBI's nixing of the 10mm had nothing to do with handling and everything to do with internal politics of the FBI with regard to gun contracts with S&W and the like. The information for which comes directly from people who were involved with the process back then and there's some good write-ups on the net to be found with a little searching.
Per an article found on the interweb:.
Ed or shibumseeker, do you reload 10mm?
Do you find a big loss or any negative aspects from the shorter barrel?
I'm considering a Witness P Carry, but have not found information (online) if 3.6" barrel is what I want to watch giant flames or reduced velocity from a pricey cartridge.
Probably not an issue, but wanted to get your experience. Thanks.
