I much prefer the lines on the older internal extractor Hi Powers. As much as I hear people saying that the extractors are prone to breaking I have only heard of two and one of those was someone dropping a round in the chamber and releasing the slide. 1911's do not like that either. I expect the Hi Power internal extractors are just as robust as the 1911's as long as you do not abuse them. It is just that they are so hard to find. I picked up two from a gent in Australia a couple years ago, so I am set.
