I have never seen the .45 but can you use the small backstrap for the 9mm on the .45 to try to make the grip a little smaller? Also is it true that the small backstrap on the .45 makes the .45 grip fill like the 9mm with the med. grip on it?[/quote]
No, I am saying they are the same backstrap. The difference you are experiencing is because the .45 is a longer round and the grip is therefore a little bit longer front to back. YOu cannot change that.
