I bought 2k of their 9mm 124gr FMJ and so far have been very happy with the quality of the ammo. The 9mm has a steel jacket, perhaps so does the 45? Either way I would guess the 45ACP to be excellent quality as well.
Applied Ballistics in Lafayette started handling the RWS ammo. Lots of it gets shot in the range. It seems to be a good brand of ammo, clean, dependable and accurate. Reasonable priced too. Some of the other european stuff is traditionally really high priced.
