10mm to me is pretty much the perfect hand loaders cartridge and an all around great cartridge otherwise IMHO. You can build up a gun to take nuclear swamp fox loadings or keep it tame and have +p+ .40 going on from WWB. Going from the super fast 100gr epansion defying all copper phillips heads, to monstrous 220gr hard cast black bear slayers going 1200 fps and just about every stop in between. 10mm covers nearly every base for every handgun purpose as well as having some options that have a pretty great capacity sticking around the 15 mark in a full size. (some aftermarket glock mags I own hold 30 rounds or so, but it's comically over sized like a g17 with a 33rd mag sticking out of it.) Light and fast 135gr going 1600 fps hits harder than 357 magnum (as all full house 10mm does) and dumps all energy into the target for a devastating SD round, but pretty much all loadings between 135gr and 180gr do that quite well. Really, I feel 10mm hits all the bases for power, but some bullet designs require you to load down a bit (looking at you Hornady xtp) to keep from rending the bullet into 20 tiny pieces and a stumpy mess before it reaches it's resting point in fleshy mediums. Which leads into the next point, loading the 10mm down you can take things as small as rabbit and squirrel with proper shot placement and it benefits greatly from a suppressor as well. While not nearly subsonic, it is still hearing safe without HP in most instances. All in all, 10mm is the 357 mag of the auto loading world and 15 rounds of 357 is much better than 6 (or 8) in my opinion. More and more 10mm guns are coming out yearly and I don't see it going away any time soon. My
