Welcome. I agree with what Tom ("theirishguard") has said, and I will also recommend something which he would be too modest to suggest. When you purchase your R9, you should purchase it through him. If you do not reside in Texas, your local FFL can coordinate the purchase with Tom.
Tom's business, Irish Guard Firearms, is a sponsor of this Forum, and you have probably seen its banner advertising at the top of the web site. You can contact Tom at

The R9 is the smallest and lightest quality 9mm semiautomatic pistol yet produced. I own one of the earliest models, trust it completely, and consider it to be a masterpiece of design and function.
