Agree with @JC_68Westy. I will add another perspective.
+P ammunition has been made by the major manufacturers since the 1970s. Super Vel was making +P back in the 60s. Using +P will accelerate wear on a gun even if its +P rated. On the other hand I know people who have shot 1000s of rounds of +P through guns not rated for it and have had no problem.
+P will give you more muzzle blast, recoil, and therefore reduced controllability in a small frame gun. Along with accelerated wear. For that you get MAYBE 50-100 fps more.
For a long time I've used a target velocity148 gr hollowbase wadcutter as a defensive load in small frame 38s. It has several advantages:
1. The bullet is already in an efficient shape. A hollowpoint has to expand a bit until it gets in the shape the wadcutter starts out as.
2. Adequate penetration. The hollow base design goes a long way toward keeping the bullet from tumbling in the target. That's how it gets good penetration even though it's starting out at only 700-725 fps from the muzzle with a 2" barrel. Gets about 14" of penetration in ballistic gel which is adequate.
3. It is easy on you and your gun. Low recoil and muzzle blast help controllability you need for subsequent shots.
FWIW Jim Cirillo who had been in more gunfights than most people was always on a quest for a better bullet. Most of his designs looked like...a wadcutter.
I use +P in k frame or larger 38s and +P+ in 357 magnums. If I want more power I'll go to a bigger gun. I see no sense in +P in semiautomatic calibers. Semiautomatics are designed to operate in a certain pressure range. I've seen tests, conducted by the manufacturers, which show their +P version of the same bullet going 50-100 fps more gave little more penetration or expansion, if any, than their standard pressure ammo.
Food for thought.
