Regarding your holster question, I don't think you'll have any issues there. They haven't changed that much, should be pretty easy to fit. Finding one that is comfortable and meets your personal preferences might be a challenge but that goes for any gun.
That's why we all have a drawer full of holster from the past. Great rigs that just didn't pan out.
