Hi! nice to have a native 627 in this thread! Nice pic's. Here also I tend to see that the barrel is a bit excentric with the bulge in the frame.
Saying that I will be fine, is that with the conversion or do you mean with the ammo? Both is ok. If the conversion is not gonna work it is nice to know the choice of a 627 is backed by good results with almost any ammo you can get into it.
