BudsGunShop.com - Which back strap comes installed?

Mine came with two backstraps the smallest one was installed. Very easy to remove and exchange though, just have to remove a pin and it pops right off. Hope this helps.

Louis, (2) back straps and the smaller of the two is installed. You can see this at 14:50 here of the case contents : youtube.com/watch?v=VoGMUWX8exI

The medium backtrack comes installed but it is as quick and easy as removing 1 pin, To remove the current backstraps and install the new one
