The short answer is yes. BUT, that's not enough info to go out and buy barrels from Galazan.
First, what's the serial number of your gun. If it starts with 470xxx, you can stop right now. These are Italian guns and any bbls Galazan has will not fit, period.
If, however, your gun is a 471xxx, you're in business. There are two frame sizes, 20ga and 28ga. You can fit 16ga and 20ga to the 20ga receiver....NOT 28ga. The 28ga frame will take 28ga and 410ga bbls (you CAN NOT fit 20/16ga to the 28ga frame).
The 471xxx guns are with VGM receivers and Krupp barrels. The specs are different. You can not mix and match. Galazan has Krupp barrels and these are a great buy.
Gunter Pfrommer is the best man to do the work. He is in Rocky Mount, VA. He was the key man behind the redesigned (471xxx) ICD and knows these guns better than anyone.
