No wrong choice
The 9mm 1911 is perhaps one of the most enjoyable handguns in the world to shoot. My thoughts on the RO are documented on this forum. Great gun for the money. You will undoubtedly find things you want to change about it. If you know what those things are ahead of time, it might make sense to save up and get a different pistol ( like the STI Lawman ), but it is a good buy and you can customize it over time if you are into that kind of thing.
Mine has had a magwell added and blended, sights have been vigorously filed down so that they aren't so sharp, Dawson front fiber optic, vz grips, and it is about to get front strap checkering and a few cocking serrations added to the front of the slide. Then it will get a new finish. All in all, I'll be in the pistol for well upwards of $1000, but it will be EXACTLY what I want and I was able to shoot it and get to know it while I got it there.
