    Not that I'm criticizing. I've got .38/.357, 9mm and .22wmr. Not to mention 7.62x39, .410 and .22lr.

    I'd shop around a bit, and see if you like anything you already have ammo for. There's plenty of good compact guns in those.

    .357sig is cheaper, and WalMart usually has some in stock. At least they do locally.

    You may not like guns. You may choose not to own one. That is your right.
    You might not believe in God. That is your choice.
    However, if someone breaks into your home at 3AM the first two things you are going to do are:
    1) Call someone with a gun.
    2)Pray they get there in time." - A wise man

    Owning both and having carried a S&W 1076 on duty for a few years I prefer the 357sig round. Most LE Agencies using it report like a 99% one stop shot ratio with the Speer Gold Dot 125jhp LE round. The sig gives you a push backwards with virtually no muzzle flip allowing you to get back on target very quickly and has a very flat trajectory which is good for longer shots. They are both expensive rounds to shoot but the 10mm can beat you up pretty good depending on what round you use and can be a bear to get back on target fast. Another advantage pointed out is that with most of the guns on the market you can do a simple barrel change and have a 40s&w, with the M&P you can also get a 9mm barrel provided you have 9mm mags. Three guns in one, thats what I call a good deal.

    Go with 10mm; get a Glock 20, and then get a .357Sig conversion barrel.

    Even better, get a 9x25 Dillon conversion barrel...

    With the right cartridge, what 357SIG gives you that .357 Mag does not, is true .357 Mag performance in semi-auto capacities. I can carry 46 rounds (3x15 +1) of 125gr 357SIG JHP at 1450fps. Much easier to carry 2 spare mags than either 5 or 8 speedloaders.

    As far as switching out to .40S&W goes, I'd choose a platform designed to handle the normal pressures of the 357SIG, and add a .40S&W barrel, rather than the other way around.

    Or, you could go with 10mm.

    I find that 357Sig is a bit more finicky for reloading. 10mm does use .40cal bullets so you do have a lot of options. If you get 10mm it makes sense to reload as you can make up some potent critter defence rounds and carry normal JHP for around town.

    So are there expansion issues with .40 caliber bullets going at 10mm speeds?

    I'd go with the .357 SIG. Designed specifically with self defense applications in mind, which is something you haven't been able to say about 10 mm for quite a while.

    I thought the 10mm was designed with SD in mind also. Was the design changed? The 10mm was designed with SD in mind. There, I said it. Now it hasn't been quite awhile.

    I really want to like 10mm, but the simple fact is there just aren't that many guns chambered for it.

    This.

    You can also buy a drop in barrel for the .40 and have all 3
