What made you buy one?  

I am trying to decide whether to buy a 10mm.  I don't plan on hunting with it.  It would appear that I want it for the best reason of them all.  Just because I don't have one yet.

I'll proabably stick to my .45ACP for home defense.  Does the 10mm offer any advantages over the .45 for home defense? If all you are doing is taking it to the range to shoot, do you find the ammo to be cost-prohibitive?  Do any of you regret getting one?

Thanks

Metallic Silhouettes, which I never got around to…

I hand load so ammo is never a factor.

I carried it a few times, but with 2 .45s not much point in carrying a 10mm.

Mine is a stainless Delta Gold Cup, sure is pretty!

......because 9mm was just to small

Cuz...  it was the other cylinder in 38-40 that I was really interested in.

Because all the other calibers didn't have enough cowbell!

Well, if the bad guy is wearing body armor......
10mm is more of a hunting round, maybe a bit too much for indoors selfd defense. A .45 ought to be fine but if you want the extra power available a 10mm will give it to you in spades.
Oh, the muzzle blast from the 10mm might give you an extra edge in sheer psychological effect.

I want a S&W 1006 to go along with my 4506.  Not much desire for a 10mm beyond that.

I've owned a Colt DE for about 16 yrs.  I lusted after then ever since I saw the first DE in the gun rags.

Most factory 10mm ammo is .40 power, though you can find better stuff if you look (I used the Winchester 175 STHP or the Hornady 170 XTP, both are pretty hot round, the Win is about 1200 fps and the Hornday is about 1250)

10mm ammo can be hard to find on a store shelf (I reload, so not a problem for me)

10mm does not really offer any advantages over .45 for antipersonnel use, except a flatter trajectory at distance.  

If you want something for HD, a 12 ga with a light (I use an 1187) beats any handgun for effectiveness.

Of course, the best solution would be to buy a 10mm anyway, simply becuase you want it!

If you plan to shoot the 10 fairly often, you should learn to reload the ammo, because 10mm is expensive when you find it, it's not like the more common 38spl, 9mmPara, 45ACP etc which can be pretty reasonable when it is on sale.  And the availability can be spotty.  To reload 10mm, doesn't cost you much to load than say 45ACP, of course 10mm rounds will take a tad more powder.

I bought a Kimber 10mm stainless target for the hell of it, and it's definately my favorite pistol. Although I must say it came with the worse sights I've ever used.  

Ammo isn't that hard to find, most stores will carry Blazer 10mm. I found that many GI Joes stock Remington UMC 10mm for a pretty decent price ~$15.00

Sort of makes me inclined to pick up a Glock 29 for a CCW.

10mm for animals and long shots

.45acp for people and close in

my rules of thumb

h/w, my G29 would not be a bad choice for inside the home, just not my first
