After the work last night I went to the range this morning. With the rear sight all the way down it shoots 3" high at 15 yards. Using my 44 special 240 grain l.s.w.c.s over 7 grains of unique. I foolishly didn't take any other 44 stuff, but will fire it with different loads before deciding on a direction to go with the sights.
I like the idea of the cylinder and slide extreme duty rear. If they make one lower than the factory r. sight that would be just the ticket.
My best group at 25 feet , slow fire d.a. ,,,,,
