I personally have a PGC Springfield Operator Aluminum slide and it did take some work to get everything to fit. It wasn't the hardest thing to do but it took alot of tinkering to get everything to work perfectly. At least I can field strip my gun really quick now. One other guy on these boards that has a PGC slide is Jugglez. His Hi-Capa has the silver version of the Springfield slide which should be the same colour as the slide you're interested in. Images of his gun can be found
