There have been a lot of reports of cracked frames in these guns. They crack between the slide stop and mag well. Subsonic's too light to make it function. Everyone that I know says the they like CCI mini mags in their 1911 conversions. Good luck finding anything now!
I own a few High Standards and compete in bullseye with one and have shot as high as master-level before (was having a great day = usually stay at expert level though) I would never run anything over 1100 fps in these pistols because they are old/valuable,and too much speed makes acccuracy suffer. If you didnt already know,you can buy after-market barrels with integrated rails built on top of them for optics mounting. Takes about 30 seconds to switch them out. Brownells sells them.
