I lost my train of thought while writing my last post and didn't touch on the original point I was going to make. You mentioned this was your first handgun. For a first handgun purchase, I wouldn't recommend either of the two you mentioned. I find a lot of people buy their first HG based on A) looks or B) some well written article or forum post touting the merits of a particular model. It is critical with your first purchase that you get your hands on a variety of HG's to really hone in on what suits you, not just what looks cool or that someone else said was great (not saying that either is your motivation). When I say hands on, you have to get actual range time with the models that interest you after you hone in on specifics that suit you while handling at the counter. If you don't have a local range that has a rental available of a particular model you are interested in, post a listing on Armslist and offer a free round of shooting to someone with that model or post a BB message at your local range. I have had success with this numerous times.
All that said, I put an average of 500-1000 rounds, depending on time of year, down range each week. I have shot many different handguns, in just about every caliber ever produced. I can tell you first hand that what I gravitated towards many moons ago is not the type of HG I shoot today. Granted, I own many but the fact remains that my motivations drastically changed as I gained experience with various different models.
The 9mm's I would look into as a new buyer and have recommended to new purchasers, in no particular order, would be the Sig P226, the FN FNX-9, the Walther P99 and the Beretta 92FS. The Beretta is uber reliable, feels good in hand and builds confidence at the range. The P99 has one of the best stock triggers out there and the ergonomics are excellent. The FN is an underdog but offers similar features to the ones your mentioned and it is one of the most reliable and flexible handguns made. The P226 is all around nice. It is the firearm of choice of many in law enforcement for the sheer confidence it brings but it's in a different pricing category than the others.
I hope this helps.
