I'm afraid that's impossible to say without knowing more about how you intend to carry and what you intend to hunt and how big you are.
A lot of folks like the Glock 20, as it allows the use of a 6" drop-in factory barrel for hunting. It also holds 15+1 and its polymer frame moderates felt recoil. It is quite large through the gripframe, however, and is difficult to use if one has small to medium hands.
I carry a S&W 1076 (with heavy recoil springs and Double Tap ammo) - it's heck for stout. A lot of people don't like the S&W system, though.
Second what Erich said. A 6" tube makes it legal for hunting in CA, but isn't necessary everywhere; check your state regs. It's another sop from the antis who don't want "concealable" pistols used for sporting purpose. I like the 1076, as he does, because it's a pretty good combination of portability and power - scaled appropriately for the cartridge and the average human hand.
Of course, if you have oven mitts for paws, nothing wrong with the Glock, as the wide frame does increase the surface area at the web of your hand and make it seem softer recoiling even though the actual recoil might be greater due to the light weight.
Bob Serva and his crew at Dan Wesson is, once again, producing Dan Wesson's Global Hunter. This is a 10mm with a 6" match grade slide/barrel assembly. It is the best "hunting" 10mm pistol for the money.
Can't find it on the "Dan Wesson" section of the CZ-USA site, and a call to their 800 number says, "what?" I do know that they are planning on building the Razorbacks again (not that I let the one I own out of my hands, so no need to buy another one) but if they are building the Global Hunter, tell me where you heard that so I can order one. Dave (who is waiting for his hopefully to be delivered soon Kase Reeder Ultimate 10mm which is the only currently available -- albeit custom built -- 10mm with a 6" slide I am aware of.)
"best" probably might mean something different to each of us and I don't think I would be prepared to argue against someone else's choice if that was what suited them.
I have several 10mms and am an early experimenter with the cartridge (in fact I got to shoot the prototype Bren X using ammo cobble up in .30 Remington cases).
The Glock sure makes sense. Mine is certainly accurate. But it is too big for me (my hand) to control the trigger in rapid fire and the muzzle flip is also just a touch over the top (no big surprise, I cannot control my G-17 as well as I control my 1911). That said it is a very fine line, if you don't really shoot that fast they are all pretty comfortable. The 20 & 21 are also just a bit "fat" for me but then who am I to criticize :-[
A 1911 makes a fine 10mm. All of mine are Colts but I do have a DW .45 and one in 10mm should be just fine. Have seen some 10mm Kimbers with adjustable sights...those might make fine hunting weapons also.
My Bren is accurate and has a great trigger and would certainly suffice for both hunting and defense but I get the impression that it will not take the abuse of a 1911.
I have a Witness in 10mm also. Pretty accurate and maybe just a touch tougher in the slide than the Bren (there are some square corners and thin sides in the Bren that worry me).
Any of them will proably work. It is a fine cartridge for the purpose you state, though I prefer the .45 ACP for both uses (then again my handgun hunting is done at fairly short range).
