I don't think I'd use this gun for my primary weapon for huntin bears. Here are the numbers.

.357 Sig was designed to provide 125gr .357 Magnum performance out of a service sized semi-auto.

It probably used to match it, but now it is about 100fps slower than the magnum in most factory loadings.

.357 Sig is commonly 125gr @ 1350fps
.357 Mag is commonly 125gr @1450fps

not to mention .357 mag can use heavier bullets than .357sig, up to 200gr even. .357 Sig maxes out with 147gr and even those are harder to come by.

I know it is also about bullet placement but this wouldn't the time to practice

Yes sir, I think you would do just fine with that.

Here is some info on that.

At full potential, the 10mm Auto produces energy a bit higher than an average .357 Magnum load and below standard .41 Magnum. The cartridge is considered to be high-velocity, giving it a less-curved flight path ("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.[12]

Some commercial loadings are as follows:

  • .357 Magnum: 676 ft·lbf (917 J) for 180 gr (12 g) @ 1,300 ft/s (400 m/s)[13]
  • 10mm Auto: 750 ft·lbf (1,020 J) for 200 gr (13 g) @ 1,300 ft/s (400 m/s)[14]
  • .41 Magnum: 938 ft·lbf (1,272 J) for 250 gr (16 g) @ 1,300 ft/s (400 m/s)[15]

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 offering 10mm load closer in performance to the "F.B.I. Load" than the full power 10mm; these still offer sufficient power for defense applications, yet their recoil is more comparable to the .45 ACP in similar guns. A few smaller companies offer full-power ammunition for this chambering. With the appropriate load, the 10mm is a capable medium game hunting cartridge at moderate handgun ranges

The 10mm Auto is suitable for hunting medium-sized game at moderate ranges, is certainly more than adequate for defensive or tactical use, and is one of the few true semi-automatic, rimless cartridges that is legal for hunting white-tailed deer in many U.S. states.[16][17] Author Chuck Hawks stated:

"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." [ 18 ]

Today, the 10mm Auto cartridge is generally used to fend off medium-sized dangerous animals, as a high-powered defensive handgun, and for hunting, especially by those who prefer the flatter carry profile and higher cartridge capacity of an automatic pistol versus a magnum revolver

I would definitely go with the lonest barrel availible.
