You did a really nice job cutting that magazine out of the gun! I keep looking at it and thinking about it but ill probably buy a jewelers saw first.
I ended up printing the magazine again vertically because I had too much ribbing on the bottom from supports....if I ever get some coffee in me ill go grab it off the printer and make sure it came out nice, lol!
edit: It didnt work, the lower areas of the bottom ended up just slots...the rest is beautiful, so ill try again and run it a bit slower and try 100% infill instead of 30.
