Try them all and I'm sure the pistol will tell you what it likes by either feeding and extracting or not feeding and extracting. I would recommend Blazer or WWB for starters and then whatever is cheap for break-in and general target practice. YMMV.
I have used Remington UMC and WWB. I like the Remington UMC a bit better. I just bought some Fiocchi, so I will be trying that. Fiocchi works well in my Beretta 92FS. It has a hotter load than UMC or WWB. Blazer Brass seems to work also.
