As noted above, "there is a wealth of information to be found here".
There is also a wealth of misinformation to be found here-----such as, "but stay away from +P or +P+ ammo".
I don't know the first thing about +P+ ammo, so we'll just talk about +P---and we'll talk about the regular ammo too----as it was back when your gun was made---and as it is today.
For openers, we'll talk about the "+"------they're referring to "pressure" there---what drives the bullet through the bore, and which too much of blows your gun into little pieces, and hurts you. That's another thing I don't know the first thing about, except that there's a DIRECT correlation between pressure and the velocity of the bullet---and I DO KNOW about that. I know about it today---and I know about it from back when your gun was made---------and it's "verrrrrrrrry interrrrrrrrrresting", as they say. We'll talk about it "apples to apples" too, which is to say we'll talk about the exact same load---the regular, everyday 158 grain bullet load.
Okay, here we go------------------------------regular ammo first.
Muzzle velocity from back in the day-------------858 fps (from the 1925 S&W catalog).
Muzzle velocity from today-----------755 fps (from the tables in the Gun Digest)
Now for +P from today----------890 fps (from the tables in the Gun Digest)
WOW!!--a whole 32 fps faster than from what it was back in the day (before they cut it back for whatever reason they cut it back).
After sitting and staring at stuff like this, I got the idea they cut it back so they could bump it back up, call it +P---and charge more money for it.
What's your idea?
Now just for grins, let's talk about the Plaintiffs Bar for just a bit---they're the folks who've been to Law School, and make their living by helping folks who've been injured, or had their property damaged by somebody or some thing made by somebody. They help them by suing the pants off the bad guys. As an aside, I can guarandamntee you the folks who make +P ammo know all about the Plaintiffs Bar---and there's no way on God's green earth they're going to put out a product (.38 Special ammo in this case) that's going to end up with them sitting in front of a judge and jury. That's because their Momma's didn't raise no dumb kids!!
The bottom line here is +P ammo is perfectly safe in any .38 Special handgun ever made-------or else!!
+P ammo is made to sell to folks who think they're getting something special---and they are----now. But there's nothing special about what it is compared to what it was---before it was changed---so they could change it back---and charge more money for it----your money---which is now their money----which is the name of the game!
Does all this make any sense? Well, it makes sense to me. Your reaction is yours.

Damn!! I forgot to vent my spleen about the new guns----rated for +P. Can you think of a better way to get some more of your money transferred over to their money? A hell of a deal!!
