9 mm gun, what to get?

Honestly you have a ton of options out there these days. I would go to a range that has rentals so you can see what you like and shoot the best. Also check with any friends who are into guns and see if you can set up a range day with what they may have. You want to make sure it's comfotable and all the contols are easy for you to manipulate. The 92FS/M9's are great full size guns that will hold up for many thousands of rounds. Alot of good guns out there like Ruger P series and SR's, Kahrs, Glocks, Springfield XD's- etc., FN's, CZ, HK, Smith & Wesson M&P and SD's, and even some of the new stuff like Caracals. Besides it will be fun going out and shooting a bunch of different guns and a boatload of ammo!
