When you get reducer sleeves, always check the barrel of your gun to see what kind of reducers were originally delivered with the barrel. The important dimensions of reducer sleeves that can be screwed into the barrel are:
1. the length of the part of the reducer sleeve that goes inside the barrel and
2nd thread location in the reducer sleeve.
