Tarrant, don't fear the +P in your revolver. It was made for it.
Never mine the hyperbole of the weak and lame 38 Special, or reclaims of +P being nothing but a minute increase in an ineffective round.
The +P ammo of major manufactures will be fine, and probably the best choice for self defense use. You can always practice with standard loads anyway.
Only when you move to the boutique ammo makers that use the +P, or +P+ rating as advertising hype to make people
think they are making a more powerful gun out of what they have might there be a problem. Most likely not though because they are probably loading their "hot" ammo to the very upper limits of the SAAMI standards. Unlike the major manufactures who leave a small margin of error for their loads.
The most important thing is that you find an ammo that works well in your particular firearm, and that
you can shoot well with.
All of the Mall Ninjas, and world savers can have all the super ultra performance +++++P Magnum devistator ammo in the world. But if an individual can't hit anything with it reliably, it is useless.
Use the best ammo
you can shoot well with.
My personal choice through a lot of research of ballistic gel tests, and my own accuracy tests for carry in my Ruger LCR used for Winter coat pocket carry......Speer Gold Dot Short Barrel +P
