Magazine feeds well. Some fitting may be required for Mark 1... I had to do just a little filing and polishing on the mag to get it to release from the magwell. I think these are made for models with the mag release button rather than bottom latch, but they work with Mark 1 if your'e willing to do a little fitting.
