Purchase two of what ever 1911 platform you are committed to carrying. You'll need the second one for when the first one starts acting like a spoiled child.
I would never outfit any department with a 1911 unless I had a Master 1911 gunsmith in the armorers room or where one myself. They will need more attention than any other duty weapon that you have ever carried. If your a dept that actually takes their pistol shooting skills seriously and puts thousands of rounds down range you will need to replace extractors, ejectors, main springs, sears, trigger adjustments, barrel links, barrel link pins etc etc, etc. This requires the operator to know how too, or have somebody on staff that knows "how too" fit parts, grind, tune and a host of other requirements to keep the pistol running smoothly.
If you just want .45 APC caliber there a host of other low maintenace pistols available. It's your life on the line. Personally I'd just carry a Glock 21/21SF or M&P .45 ACP full size.
not to mention, single stack limits your firepower. How fast can you execute a mag reload under stress with an adrenaline dump ???
For your benefit I have to say this. RIA guns may be cheap but for a reason. I have yet to have one that has run a full mag smoothly without a type II failure, even with CMC mags and Wilson mags. I wouldn't trust that gun as a paper weight.
