To the OP,
My dad owned an RIA 10mm 1911 and it was a real shooter. Fully supported barrel (great support, too), reliable and accurate. He didn't even change the RSA although, as you have opted to do, would change the RSA to a 20lb or so. Otherwise, a great gun and a great value.
My recommendation: buy some more mags and AMMO!!! Shoot it!!!
Enjoy!!
