I use the exact same ammo in my 41 as my custom "Bulls eye" 1911. Factory Glock barrel does not lead.
No need to change. 41 MOS could be used in CO, Limited 10, Production and Limited (major). Taylor Free
lance has mag extensions. 41 fits same holster as 35/34.
9mm would be less expensive to shoot in the long run. But you are going to have to tool up to load ammo.
