OP...... this post will not help you, you will read it, will read all the replies and be as confused or more confused than before you asked. A question like this only encourages the people posting to tell you their opinion. Everyone is right,, it's what works for them, but that may not be what works for you. Unfortunately there is no correct answer, you have to buy what feels right for you, and like most of us, unfortunately your first gun may be replaced rather quickly. Once you start regular shooting you will come across another that seems more suitable or perhaps that first gun isn't what you thought it was once you start using it.
Some love their striker fired polymer pistols, some prefer all steel firearms, a lot of what you buy has to do with your budget. Some say to start with a 22, some will say that's a waste of money........ and so it goes.
If you can spend time at the range with buddies, try their guns, most shooters love to have someone show interest in their choice of guns, kind of like a proud parent ! lol
Only thing for certain, one won't be enough ! lol
