Underwood 9mm +P+ 115 Grain GDJHP Test

[Ljutic]

Not something I would shoot every day, but day-um that's a boat load of energy from a pocket 9mm.

I will admit running a few Speer GD 115 grain +P+ through my PM9, but does anyone know the official Kahr stance on 9mm +P+ in the PM9 and CM9. Even with the 3" barrel I bet this load would make close to 1300 in the PM9.

My Glock G27, with an OEM G33 3.46" barrel,
only pulls ~1300 fps with LE 125 gr 357 Sig ammo.

A 1300 fps 115 gr 9mm from a 3.0" barrel is really smokin.
Personally, if I wanted that kind of power, I'd just get a PM40/CM40.

Kahr does not recommend using +P+ in any of their guns because +P+ does not have a SAAMI spec.

After watching the vido and reading about Underwood I ordered some, got here in 2 days. Checked the vel and got 1330 fps from my 3" Kahr also got perfect expansion. Felt recoil was about like Cor Bon 115+p but about 100 feet faster. No signs of too much pressure. By far the best defense load I've shot in 9mm at least in short barrels

No gun manufacturer is going to reccomend +P+, not any, none, zilch, nada. It is a liability issue. If they said their guns will shoot +P+ and you blew up your gun and lost your shooting hand and your aiming eye, they would be sued and would lose the suit.
Even though many guns can shoot them.:84:
