And a Hound Dawg Howdy to you from SC!
There are two types of ammo....
'Range' ammo that is usually (somewhat) inexpensive that you practice with. Usually it is full metal jacket (fmj)
'Defensive' ammo that you use in cases of self defense. Usually this is jacketed hollow point (JHP) variety.
In a pinch, ANY ammo is good ammo for any purpose.
Since we all need practice, it doesn't make sense to shoot up more expensive ammo just to shoot paper if it can be helped.
However, you do need to put some of the defensive rounds through your gun to assure reliability and so that you know how they will feel when you shoot.
Any common, reliable brand of defensive will do. Remington, Winchester, Federal, Speer, Hornady. Don't pay big bucks for 'boutique ammo' unless that's all that's available.
Do not use any ammo that is labeled +P+. +P is ok, as well as standard loading, but +P+ is loaded to a higher pressure than many guns are designed for. The instruction book with your pistols should give recommendations about what to and what not to use.
