Shouldn't you use an AR in an AR-based training school? I'm not sure anyone would seriously use either the CX4 storm or a 995 in a real CCW or assault type role, maybe in .45 caliber but the AR has put the pistol caliber carbines out to pasture. Again you seem to be the only person who has personally seen 2 995's go kaboom and maybe you would like to share the details. The Hi Points are cheaply made but the design actually seems pretty safe and reliable.
Why is 9mm, 40 SW, and 45 ACP deemed inadequate for Close-quarters or assault? In a military capacity, it has limited uses. But in a military capacity, an AR is pretty limited considering M249 machine guns and M2 Bradley IFVs.
Now, for real police work or self-defense.... the 9mm has been employed and still is used by SAS for dispatching terrorist. The simple fact of the matter is that knockdown power is irrelevant when you shoot someone multiple times in vital spots at close range. The key factor is being able to skillfully place shots very quickly, amongst many other things. For those that hate the 9mm, the CX4 is also available in .40 and .45. Having a CX4 and a PX4 in 40, with (4) 17 round mags is quite a loadout (one in the CX4, one in the PX4, and two in a mag pouch).
The CX4 has many advantages over the HP.
1) Interchangeable with PX4 or 92/96 mags. I love the PX4 and am a huge fan of the 92/96. Having interchangeable mags is a definite bonus.
2) Ambidexterity. I am left handed. I don't like shooting autos because I tend to eat ejected shells all day long. The Beretta is completely reversible.
3) Comfort and ergonomics. The Beretta stock is just much more comfortable IMO.
4) Customization. With all the rails, it is very easy to slap on a red dot and light.
5) I once had a HP 9mm. I don't even want to talk about it.
