Yeah, Northridge is pretty consistent NOS parts supplier. If anything is reproduction it says so. Prices aren't too bad. I checked last night and I don't any of either left after I updated mine. I also thought of one item you might want to get if you are ordering hard parts. Operating Slide Stop. It is the little button near where you pull the slide back and allows the slide to lock back. I forgot that I usually replace those if they are worn and they do wear out at the bottom. http://northridgeinc.com/store/index.cfm/c128 The mag catch is M1C-52 for the M2. Safety is M1C-37B. Slide Stop is M1C-22 if you decide to get it. You can just check and see how yours works to see if you need or want it.
