If you need a firearm to prove that you have testosterone in your system, buy a Glock. Better yet, buy a 1911 in 10mm and hold it in your teeth when you fire it.

Don't forget to sneer at anyone firing anything more with less muzzle energy than your pistol.
If you're secure in your masculinity and don't feel threatened because some other guy might display more machismo than you, buy the gun that fits your hand. Even if it is an M&P with the small backstrap.
As an added bonus, when you throw the small backstrap on your M&P, it'll fit the hands of the cute girl firing the Ruger .22 next to you, and all the Glock snobs will be going green with envy as she fondles your pistol.
Seriously. Do whatever you can to handle the various candidates, and buy the one that fits your hand.
Also bear in mind that with the large backstrap, the M&P may well fit large hands better than a Glock 17, depending on finger length and about a dozen other variables.
Don't let the Glock snobs make you think that other pistols are inferior...they're just bitter about being teased by the SIG snobs.
