I've seen several done that way, and own and shoot one as well. Doesn't seem to hurt accuracy, BTW.
Whoever did the work did a good job. (I've seen some rather poor workmanship on too many to remember) But he turned the rear of the cylinder to get the headspace. The lack of a serial number on the rear of cyl. is what got me to really inspecting the pistol closely, rather than just a cursory examination. (It is not mine, belongs to someone else) When I get a chance, I'll take some pics and let y'all experts cypher the various markings.

Thanks for all y'alls input,
