Glock 20 SF

Question
I am looking to buy a gun, and have came across the Glock 20 SF which has caught my eye, and I would like to have an expert opinion on the gun if you can help. Pros and Cons + any other gun you might recommend me checking out.

Also if you can answer this question it would be great...I have seen better prices online for the Glock 20 SF than at local stores. What is your opinion on buying guns and/or ammo online, have you done it before.

On an online store called Proguns.com I have seen the Glock 20 SF at it cheapest price I have found at $526.99. Do you know anything about this site or company?

Thank You very much for any halp you can offer!

Answer
Sounds like a fair price.  Glocks are simple to break down and very reliable.  Not sure what you want a 10mm, I am a fan of the .45, best round out there in my opinion, lots of ammo, easy to find, cheap and very good knock down.  The round is proven.  The 10mm never caught on that much, ammo cost more and not as many types since not so popular.

Buying online still requires gun to be be shipped to FFL holder so whoever (store or person) that is going to get gun, you may ask if they can match price or get it cheaper since they will have to transfer and that normally cost a fee.
