Seems similar to the issue with pulling Null Composure from Collections results in a weapon w/o a masterwork option… Although (and I say this with personal experience in the matter) with a MW-free Null Composure pulled from Collections, it will eventually randomly become properly (and fully) MWed if left in your inventory. It’s [i][b]possible[/b][/i] that buying these weapons from Banshee and leaving them in your inventory will result in their MW roll randomly appearing in a similar fashion (although you would still need to invest the required mats to MW them fully), but as I have not personally tested this to see if it works I cannot, in good faith, recommend anyone should purchase them to find out.
