It may help the gun function, but with +P you get increased wear and tear on a gun. It's not to be used as range ammo, in part because of higher cost.

I would not run much, if any +P ammo in a Hi Point. If you gun is not functioning well (is there a reason you're asking?) with standard velocity ammo, there's something wrong with the gun.

only use +P in self defense
not at the range
even SIG has recommendation on some of their guns to use +P sparingly

many people just get a box of 25 cause they only need it for when they are carrying concealed or for home defense
not for practice

Nothing wrong with the gun, that I know of. I haven't fired it yet. Going to get ammo this afternoon. Thinking about 230gr. fmj. Any thoughts?

If I understand things correctly, your pistol is made of fairly soft, die-cast, non-ferrous metal.
While Hi-Point pistols have a reputation for reliability and accuracy, my bet is that they are not very durable. Therefore, you would not want to over-stress one.
Therefore, as VAMarine has stated, using +P ammunition is probably not a great idea.

In self-defense shooting, accuracy ("bullet placement") trumps ballistics, every time.
If you practice to hit what you are aiming at, you will never need +P ammunition.

Yes, 230-grain FMJ-bullet cartridges will work properly. So will 230-grain RN lead bullets, I bet, and they will be cheaper for use as practice ammunition.
For self-defense use, you might want to try several different kinds of hollow-point-bullet cartridges, too, and see which works most reliably in your gun.

Thanks. I do want to practice with what I'll be using. I guess that's the rifle shooter in me. FMJ's are fine. At darn near 1/2" diameter I wouldn't think lead expansion to be totally necessary. I know with a rifle, you risk shooting shooting through your target with FMJ's. But that's also 3000+ fps. What does a .45 shoot, 800fps?

Traditionally, 850fps.
Nowadays, standard-pressure rounds might make 900fps, or even 950.

Thanks, Steve. I read the post. I bought a $200.00 gun. I realize that. To be honest, I keep a shotgun for home protection. I do have a ccw. I've just never felt compelled to carry. But the world's getting crazier everyday.
