changing your slide and barrel???

[carpediem916]

i just got a xd40 4'' with the black slide and was wondering if i was able to purchase the bi-tone slide and switch them up??? If so wear would you be able to buy just the slide of the pistol??.. i was maybe thinking you would have to get one from the manufacturer of the gun..idk??

Also with the 5'' tactical barrel? would you be able to switch them out too with eachother???
