For the woods, I want more that what the 10mm has to offer.

It's a good cartridge in it's own right but I can't justify the cost and recoil when the .40 or .45 does everything I need them to do without the cost, recoil, bulk, and the sever potential for over penetration.

To sum it up, my personal feeling on the 10mm is it's too much for the two legged critters and too little for the four legged ones. Too much in one case and not (or barely) enough in the other. I just never saw what the 10mm could do for me that cartridges slightly larger or slightly smaller couldn't do already.

The 10mm was a solution in search of a problem and was more of a bastard round than the .40 S&W IMHO.
I agree with your post for the most part. I have nothing against the 10mm at all, however for carry I'm fine with the .40 and .45. If I go out in the woods, I'm carrying something with a good bit more power than the 10mm can offer, although there is nothing wrong with hunting with a Glock.

If there was a huge difference between the 10mm and .40, say 400-500 fps and it used bullets designed specifically for the extra speed, maybe the 10mm would have more merit with me. As it stands, there's maybe 150 fps difference between them both (loaded hot), which brings me to the issue of penetration.

I don't think the 10mm generally suffers from over penetration with JHP bullets and here's why. A hot loaded 10mm (as well as a hot loaded .40) can both push essentially every JHP bullet out there beyond the velocity they're designed for. That generally decreases penetration instead of increasing it. That's not necessarily bad, but then again, pushing a bullet faster than what it's meant to be driven isn't exactly good either, as bullet failure tends to limit penetration.
