Yep. They sell out fast."Out of Stock"
At one hundred yards a 125 grain 9mm will be moving around 1000-1200 feet per second out of a 10 inch barrel, comparable to a .38 special at normal handgun ranges. I should note that 9mm is usually used with a 115 grain bullet.Is that really practical though, considering there is perennial debate about it's stopping power at handgun distances?
Not trying to knock the idea. AR9 has some appeal to me, just trying to think through the pro's and con's.

So it’s not an elephant gun but it’s very adequate for self defense, especially when you remember that the hundred yard capability on the outside of its intended use.
Math and I are not friends, but that comparison doesn’t smell right.For the people who like numbers.
For anyone wanting to calculate the foot pounds of energy on other bullets, the formula I have always used is "velocity squared, times the bullet weight in grains, divided by 450400" there may be a easier formula, but I haven't looked.
- A 124gr bullet moving at 1000 fps packs 277 foot pounds of energy. At 1200 fps it is 299 foot pounds of energy.
- A 115gr bullet at 1000 fps has 255 foot pounds of energy. At 1200 fps it is 367 foot pound of energy.
- A .223 55gr bullet at 2800 fps has 957 foot pounds of energy.
Well if it is wrong, then someone please let me know.Math and I are not friends, but that comparison doesn’t smell right.

It didn't look right because you'd made one typo, and ended up with a 124gr bullet having less energy than a 115gr bullet at 1200fps. Using your formula (which I am assuming is correct), fix as follows and it all makes sense:Well if it is wrong, then someone please let me know.
Ahh yes! Thank you. I guess that would make a bit of a difference.It didn't look right because you'd made one typo, and ended up with a 124gr bullet having less energy than a 115gr bullet at 1200fps. Using your formula (which I am assuming is correct), fix as follows and it all makes sense:

- A .223 55gr bullet at 2800 fps has 957 foot pounds of energy.
It’s questionable as to which end of the 7mm feels worseWell if it is wrong, then someone please let me know.
I will say though, in the world of projecting objects, velocity makes a huge difference in how much energy it packs, hence the reason they say "velocity is what kills body armor."
As an example, I have personally seen a 7mm Remington magnum, with an average bullet weight of 155gr, and an average velocity of 3024 fps, (the round we used was a soft nose hunting round, so nothing special) sail right through AR 500 plate at 100 yards, while the 45-70 with a muzzle velocity of about 1600 fps, and a 500gr bullet didn't even phase it.
You might feel the pain of the recoil longer.....but I have seen the long streak down the dirt road that was made by the 7mm spreading the yote's innards. I'd take the bruised shoulder any day!It’s questionable as to which end of the 7mm feels worse
It’s a devastating round. Not a great round for meat hunting though, causes too much meat destruction. Coyotes though? Perfect!You might feel the pain of the recoil longer.....but I have seen the long streak down the dirt road that was made by the 7mm spreading the yote's innards.

The 9mm is a very practical round. The issues with stopping power initially were due to using a NATO spec ball ammunition, basically a copper jacketed bullet that would zip right thru the perp without expansion, resulting in the majority of its energy being expended beyond the intended target.Is that really practical though, considering there is perennial debate about it's stopping power at handgun distances?

Eats barrels too. Not a big deal in its intended role though.It’s a devastating round. Not a great round for meat hunting though, causes too much meat destruction. Coyotes though? Perfect!
Never miss? Wow!!!
