I haven't tried 45ar but I have a couple of 625's cut for moon clips and they work just Great, 1 I just purchased here a month ago shoot's just as tight as either of my 25-2's and 625JM 4".

I have 7 N frames 2-625 mg, 2-25-2's and 3-625's for 45acp and 2 of the mountain guns have been cut, and accuracy isn't compromised one bit,If your looking to get one done by all means got for it, its great to have a MG with dual roles.

On the parts section of this forum you'll find someone selling 2-625 fluted cly., thats a good start to have a separate cylinder for the project and have the best of both worlds.


There's several gunsmiths you can get this work done from, just check this forum and you'll find a few, I'm sure a few of the guys here will chime in with some gunsmiths in mind, Just my 2 cents worth.
