I think the SW Sport will be just as good. I have seen the Sport shoot thousands of rounds without issue. They all poop where they eat and if you don,t run them wet or clean them you will have problems just as the Colts did in Vietnam. Oil&clean is the key to all Ar,s problems. I use Mil-com white lube and when that runs out back to Ballistol muti-purpose Sportsman oil. This oil is about the best you can buy for firearms. Used by the German Army in ww2 in all weapons from MG42 to p38's in all weather all fronts.
