Good decision??

With Colt and GLOCK you are reading for the goblin hoardes . . .

Colt over M&P all day

This.

Glock 21, it's one of the nicest shooting Glocks. Parts are easy to get, and you can even get 28-round magazines for it. The M&P would be my second choice, especially if it has the newer upgraded trigger. I personally would avoid the HS2000 45 at all costs.

Why no xdm

Why no xdm

Because the XDM isn't in the same class as the above mentioned pistols.

Why no xdm

Do a little looking around and you'll see the reasons on this forum. While I personally have never had an issue with the XD platform, the XDM platform I personally have seen several issues with. Enough so that I am generally skiddish around XDMs for anything other than range toys. Of the group you mentioned the 21 would likely be the best option of the three, in my opinion. And this comes from someone who generally is not a Glock fan so......

I can personally attest to the 6920 - A couple thousand rounds and a carbine class.. still running strong.

I would say Glock or the M&P 45 are solid as well. YMMV

Is the 40 cal hard on parts? I mean does a 40 cal pistol have a shorter service life than a 45?

Traditionally, yes. The pressure is much higher in the .40, and tends to wear everything out more quickly. I would assume you would have to shoot a ton for this to happen though. YMMV.

OK thanks man

[dylank0723]

Does it give much more stopping power than 9mm? Or enough to make a really difference
