These firearm forums always have people with little or no firearms experience ask people with a lot of experience the question; "Which Gun Should I Buy?" My response is, "I don't know until I can see how well you can shoot in the first place" How often do you plan on practicing? Do you enjoy going to the range to shoot? If you like what you're doing you'll want to practice it until you get pretty good at hitting your target. If you shoot a box a year your new gun might as well be an expensive doorstop. Do your targets look like swiss cheese or is there a ragged hole on the target where the "meatball" used to be?
You would do well to do one of 2 things;
1) Enroll in the NRA Basic Handgun Safety Course the next time it is offered at your local gun range. I took the course years ago and there are things they teach that will stick with you. When I took the course I rented a Browning Hi-Power and that's all I wanted until I found out what a decent BHP went for. When the tell you that you should have your carry gun "armored" by a qualified gunsmith at least once a year, that's a valuable piece of advice you should follow. The best thing you will learn is to rent or borrow different types of guns for 6 months before you commit to a purchase. Six Months after I took the course I picked up.a LN Sig P228 that was half the cost of the BHP. The BHP might be a little better but it ain't twice as better. That instructor knows more than you, pay close attention & listen!

2) Hire an NRA Certified Instructor for a one hour session so he or she can assess your shooting skills firsthand. The LGR should be able to recommend an instructor, they may direct you to their bulletin board or you can contact the NRA directly for an instructor referral. Have the instructor provide you with a short list of firearms that are either available for rent at the range or perhaps you have friends & acquaintances that have guns who you can meet at the range who will share their toys. It's always nice to offer to pay the range fees and pay for a box or two of range ammo.
In a perfect world, item 1 would be a prerequisite for getting a carry permit across the country. Here in Pennsy, you don't even need to own a gun to get the permit. In this situation, I think good common sense is always good but rarely common. Everybody starts out as a beginner but you don't want to stay that way!
