If you're primarily interested in handguns for defensive purposes, you're likely to choose a 10mm for the outdoors. You're also likely to never fire a shot outside the shooting range.
If you're primarily interested in handguns for other reasons such as hunting, you're likely to choose something else. You're also likely to shoot stuff with your revolvers all the time.
There's multiple reasons why I don't choose the 10mm as a primary sidearm in the wilderness. They have nothing to do with my age or level of Fuddery. I'm no stranger to "newfangled" semi-autos with high capacity magazines. However, unless you are going into battle, magazine capacity is a false god worshiped by too many. It's simply a non-issue 99.9999% of the time. Diehard 10mm fans will argue this but preference and need are rarely the same. Accuracy is another reason. Virtually any good revolver will be capable of 1" groups at 25yds. Service autos are usually going to be at least two if not three times that. Fine for something you're just going to carry but if you depend on your sidearm for camp meat or shooting at yonder rock 200yds away, it matters. The sights contribute to this as well. Service autos with coarse sights are not conducive to fine shooting when compared to the fine target sights of many revolvers. The trigger is another reason. Unless it's a 1911, a service auto's trigger is going to suck. Yes, I'm aware of 3.5lb Glock trigger connectors, I shot them for 15yrs. A Glock trigger will never hold a candle to the 2-3lb crisp single action trigger pull of a revolver. Weight. This is often touted as a feather in the polymer auto's hat but people seem to look at unloaded weights alone. Yes, an empty Glock is very light but as soon as you load the damned thing, you're equal to a 4" revolver or 5" 1911. Ironically enough, many of the same reasons why I do not choose a 10mm are the same reasons why I don't choose a .357Mag revolver either. A .44 or .45 with a 250gr cast bullet at 800-1000fps will handle 99.99% of what needs doing and do so without making your ears bleed. A serious limitation of semi-autos is their inability to handle reduced loads. The revolver does't care. At the upper end of terminal effectiveness, magazine capacity does not make up for the fact that the 10mm is at best a deer cartridge. The very best of 10mm loads are equivalent to the Keith .44Spl load, albeit with a smaller bullet with a disproportionately smaller meplat. Having 16rds does not make up for a lack of bullet mass and you can't miss fast enough to win a bear fight. When it comes to large, scary beasts, there's no replacement for displacement and appropriate cartridges for such tasks BEGIN with the .44Mag.
