The top joint in particular just doesn't move as far as it should thanks to the way the sides of his kneepads are sculpted. Once you shave the notches from the back of his knees you can force them further but it's still just not where I'd like them to be. Thankfully his torso articulation works much better once you remove some plastic from the bottom of his torso. This was easily the most important modification I made and improves the figure a lot.
This holster was ripped from a broken Marvel Select Deadpool I had around and the handgun from Arkham City Direct Two Face. I just heated and removed the old holster and carefully superglued this one in place. I painted it black and you can see some chipping off. It works though, and the glue has been holding up really well considering the handgun is a fairly tight fit.
