what's the difference to a .40?

Holds kore rounds per mag

PPQ comes in 9mm and .40

.40 is larger

Higher grain bullet

Was cut down from a 10mm

what does grain refer to on a bullet?

The weight of the round

more expensive than a 9mm?

Yes

By about 10 cents per round

I'm thinking I'm gonna go with the 5 inch barrel rather than the 4 inch on the PPQ, an extra $100 for a gun that I'm guessing will feel a little better to shoot

seems reasonable for a starter

Is it for conceal carry?

not sure yet

watched a video and they said the five inch can still be conceal carried

Just depends on what you are comfortable with

Actually now that I think about it I'm definitely going to want conceal carry if I'm out and about off base.

You would be surprised how uncomfortable it is to conceal a larger weapon with out printing the weapon

printing?

The ability to see the weapon against your clothes

Hmm well I got some time to consider it, a few months at least.

Hopefully I can get a chance to try out both kinds.

Yea i would try to shoot both calibers before buying for sure

So when you said grain refers to weight, is that change only because of the size of the bullet? I'm wondering if there's different densities/alloys

The weight of the actual bullet

9mm comes in many diff weights

40 cal does as well

I use 9mm 115 grain

This effects the velocity of the round

Grain is also the amount of gun powder used

That effects the chamber pressure of the barrel

So it's just a difference in amount of powder that causes the change in weight?
