    The first choice I have for .38 ammo for personal protection in a carry revolver. It hits shockingly hard, gel tests show it going very deep, and its both extremely loud and can shoot some big fire balls out the sides of your gun which is going to scare the shit out of all but the most persistent problem on two or four legs.

    Other guy whining would like to see higher than 90 grain...well this is 99.5%+ Cu or "copper"...it is not as dense as lead and thus does not have the same weight or grain to it. As good as it gets for what it is, unless you're going to have a longer bullet or wider bullet, there really isn't anyway to add more weight to it...it its a 9x19mm and that's all the weight/grain it will ever have being made of copper.

    Overall a great product, pricey but unique. unlike others have been tried, these are true to purpose. I would like to see a higher grain than 90 for this ammo.
