So many shooters say they love the 10mm.  But they’ve never owned one.  They say that they would, if ammo was cheaper and more plentiful. 
If they would actually step up and buy 10mm guns and buy 10mm ammo, then the Gun Industry would respond in kind.   More guys buying 10mm, the more ammo would be produced, driving costs down.  More variety would be produced.  More gun makers would offer versions on 10mm. 
But we won’t get that… Because 10mm is the Ron Paul of cartridges.

But could you imagine… An XDM, Beretta Storm, M&P, or a SIG… Anything from SIG… in 10mm?
I would buy a Beretta Px4 Storm Tactical in 10mm.  I’d buy it ASAP.  Hell, right now!
But then again, I have an active imagination. 
Because the problem with the 10mm is also the gun options are so thin, no one is really interested in jumping into the 10mm bandwagon.  Unless you like Glock or EAA, you ain’t getting a 10mm.

Here is a prediction.
Just like the first AWB brought back the popularity of the .45 Auto… I predict the next AWB will bring a surge of people to Ten Territory.  8 rounds of .45, you could have the full limit of 10 10’s. Think about that.
