I have a Uberti NMA that shoots very high with round ball at 50 yards. It is almost 2ft high at that distance with a 30gr 3f charge and .451 ball. A gunsmith I have spoken with said to remove the front post and machine in a dove tail slot for the replacement sight. I really do not care for that look on the revolver and would like to just replace the post with a taller one or build up this post. Does anyone know if the post is silver brazed in place, or pressed in.
