Ha !! That's just for the uninitiated!! I do it every day!!! Lol!!
One wouldn't normally take a hammer to a revolver unless it has a wedge! Wouldn't worry about the straight barrel. It's straight. No need to be concerned about getting it apart the first time. It won't be that hard after that. The wedge spring should have enough "meat" on the end for you to grind it flush with the end of the wedge. Then you can hammer the wedge without worrying about the spring being damaged.
BTW, are you doing all this on the kitchen table? Or anything other than a solid base? Like the floor, a concrete patio, sidewalk, fireplace, etc. A table has too much "give". I've never had this problem. After I do my " fitting " of the arbor, it may take a few "take downs" before the wedge scoots out with a hammer smack. Sometimes I'll put a punch mark on the end of the wedge for the customer to use a punch if needed the first few times.
