I wish S&W would come out with a 10mm. I have a 1006 and some other 10mm's. I think the 10 is a great cartage for power and accuracy. The reason the 10mm is not more popular is after the FBI deemed the 10mm had to much recoil for its agents (they kept asking for less powerful rounds) the 10mm light (S&W 40) was born.
With the FBI and other police deps. Going to the S&W 40 there was less demand for the 10mm's, but the 10 is far from dead.

Performance
Tanfoglio T95 Combat/EAA Witness Steel with Wonder Finish.At full potential, the 10mm Auto produces energy slightly higher than an average .357 Magnum load and below standard .41 Magnum rounds. The cartridge is considered to be high-velocity, giving it a less-curved flight path (also termed "flat-shooting") relative to other handgun cartridges. In its lighter loadings, the 10mm Auto is an exact duplicate of the .40 S&W cartridge. More powerful loadings can equal or exceed the performance of the .357 Magnum, and retain more kinetic energy at 100 yards than the .45 ACP has at the muzzle.[13]
Some commercial loadings are as follows:
.357 Magnum: 676 ft·lbf (917 J) for 180 gr (12 g) at 1,300 ft/s (400 m/s)[14]
10mm Auto: 750 ft·lbf (1,020 J) for 200 gr (13 g) at 1,300 ft/s (400 m/s)[15]
.41 Magnum: 938 ft·lbf (1,272 J) for 250 gr (16 g) at 1,300 ft/s (400 m/s)[16]
The loads listed above are from a boutique manufacturer of high performance ammunition and are about maximum for S.A.A.M.I. established pressure levels in each cartridge. Free recoil energy of the full-power loads listed are 10.1, 12.1, and 22.9 ft·lbf (13.7 J, 16.4 J, and 31.0 J) respectively for these cartridges, computed assuming a 40 ounce (2.5 lb, 1.15 kg) handgun.
Most major ammunition manufacturers offer 10mm loads closer in performance to the "F.B.I. Load" than the full-power 10mm; these still contain sufficient power for defense applications, but their recoil is more comparable to that of the .45 ACP in similar guns. However, some companies do continue to offer the original full-power ammunition.
[edit] Usage
Glock 20
Glock 29The 10mm Auto is marketed for hunting,[17] defensive, or tactical use[18] and is one of the few semi-automatic, rimless cartridges that is legal for hunting white-tailed deer in many U.S. states.[19][20] In regards to its use in personal defense, firearms author Chuck Hawks wrote:
"The most commonly available, reasonably portable, autoloader that might serve our purpose is the Glock Model G20, chambered for the 10mm Auto (.40 caliber) cartridge. The G-20 is as reliable as a powerful auto gets and relatively compact. This pistol comes with a 4.6" barrel, is 7.59" in overall length and weighs only 26.28 ounces. In recent years Glock has promoted the G20 as a hunting pistol. The EAA Witness DA autoloader is also offered in 10mm Auto and the Colt Delta Elite version of the 1911 Government Model used to be. There are probably others of which I am unaware."[21]
Today, the cartridge is used as a high-power defense caliber against humans or animals, and for hunting by those who prefer the flatter carry profile and higher cartridge capacity of an automatic pistol versus a magnum revolver.[19] It also makes "Major" power factor ranking in I.P.S.C., even in lighter loadings.[22]
Despite the F.B.I. switching to the .40 S&W, there are still a number of law enforcement agencies that continue to issue the 10mm including the Albuquerque Police Department and the Anniston Police Department. In Canada, the Alberta Sheriffs also employ the cartridge in the Glock 20.
The government of Denmark has issued the Glock 20 to members of the Slædepatruljen Sirius (Sirius Sledge Patrol) in Greenland.[23] The pistols were issued as a defense against polar bears which the unit encounter.[24][25]
I believe that many gun company's have opted not to tool up to make a new 10mm. Is due to the political climet here in America.
