I just have to say, get off the fence! This is how it went for me. I turned 21 and wanted a handgun. I new what I wanted when I went to the gun store and was dead set against buying one of those silly, ugly plastic guns. However they offered to show me one. I said "oh, I suppose" Needless to say I bought a Glock 23, Then so did my dad. Then I bought a second one, my friend bought a G22 and my wife ended up with a G23. all because I looked at the one gun, against my wishes. Now I have a Gen 4 G17 too. Love it!
My point is, check'em out, buy one you like and give it a try. My guess is it will slowly become the main gun you shoot and you will have to buy more. I absolutely suggest the G23/19 sized pistol because, as previously mentioned, they are the best looking. And I also suggest gettin it in the Gen 4 version,. that will give you a better chance of getting it to feel great in your hand.
Pick up the Glock annual at a local magazine store and read thru it. Also consider the GSSF program if you like the idea of a simple way to compete and improve your shooting as well as the chance to buy a Glock at a great discount.
Glocks are hard to beat when you add it all up. Relatively inexpensive, proven, accurate, reliable, nearly indestructible, high capacity, GSSF benefits, light weight, tons of aftermarket support, simple operation, low maintenance, good support, etc. They are like potato chips, you can't have just one! And if you don't like it, you will be able to sell it.
