Pete,I do not believe there is an Arms Museum in Maastricht.As you may be aware,Maastricht was home to some fine gunmakers in the 17&18 Century, The only trace of the cities gunmakers that I uncovered was the odd example of flint lock pistols/rifles seen in antique shops.
Regret cannot offer advice on museums in Luxemburg or other cities in Belgium.
Maastricht is city rich in history & well worth a visit; access to Liege is easy ,less than 30 mins, drive.
