I can't speak to the question that you ask, but I would suggest Wilson magazines if your budget allows. I've seen several 45's that wouldn't even feed roundball with the GI type mags, put the Wilson's in and it runs like a top. One word on the Wilsons, load to their recommended OAL with H&G68 to ensure reliability. I have seldom purchased a product that I was as thoroughly happy with.
