10mm Auto simply cannot fit inside of a 9mm size frame, whereas .357 SIG can.
For 10mm you have to go up a frame size, and for some, the grip size of 10mm is too big to fit their hands properly, which in turn results in poorer accuracy.
Also, for all the hype 10mm Auto receives, it just sort of lands in a weird spot in terms of power. Most commercially available factory loaded ammunition is loaded to FBI Specifications, making it the ballistic equivalent of .40 S&W because the 10mm FBI load was the reduced power load which was the basis of the .40 S&W cartridge. Oh, but 10mm FBI Loads cost substantially more than .40 S&W.
Boutique loads are hotter, closer to the original Norma Spec ammo, but ballistically it's generally no better than .357 Magnum at best. 10mm Auto loads which can match .41 Magnum ballistics are an Urban Legend based on some watered down .41 Magnum loads Remington offered which specifications appeared in reloading manuals.
There's a reason why 10mm Auto never really achieved mainstream popularity to match .380 ACP, 9mm Luger, .45 ACP, or even .40 S&W. Full-Power loads are better suited for quadrupedal predators like Bears than it is for humans, and the reduced power loads are no better than .40 S&W, yet they're in a longer case and cost more money. So if you subscribe to the belief that .40 S&W offers no tangible benefit over 9mm Luger, then 10mm FBI is even worse because it requires a bigger gun, costs substantially more than 9mm, and offers nothing in return for it.

Who knew?
It always seemed like a good answer to a problem that didn't exist.

It was never designed to solve a specific problem, it was designed specifically to appeal to Police Departments who favored the .357 Magnum by duplicating the performance of the 125gr .357 Magnum load which had an almost legendary reputation as a man-stopper within the field of Law Enforcement.
That being said, it definitely has its advantages, such as superior barrier penetration compared to 9mm Luger and even .40 S&W, which made it popular with Highway Patrol units in particular because it offers more straight-line penetration through autoglass, whereas the trajectory of 9mm Luger and .40 S&W tends to deviate more after striking the angled surface of a windshield.
