Hi all! New to the forum and my first post. I have a number of S&W revolvers including some newer ones that have the barrel insert/shroud method of installation where the barrel is seperate from the shroud. I recently bought a 610 which had to have the barrel properly indexed. I thought it was odd because the new method of barrle installation should preclude this. However this brand new 610 had the standard crush fit screw in barrel with integral shroud. I thought S&W didnt do this anymore?
