I apologize if this has been discussed, if it has, I could not find the thread. What personal defense ammo would you recommend for a S&W 442 .38 SPL revolver? It is rated for +P. I noticed that there are numerous rounds that have different amounts of powder. I know most would recommend a hollow point, but the "grain" is confusing me. I would like suggestions for brand, point (head), grain and any other factors I should consider.
