-Belt Mountain Base pin
-Free-spin pawl (easily modified yourself without spending the
$20+ on a new one that is modified)
-Wolf Spring for the trigger (to lighten it);(leave the hammer
spring alone)
-Bowen Rough Country rear sight
-New front sight (done yourself) following the instructions in
this article (
http://www.beartoothbullets.com/tech_notes/archive_tech_notes. htm/59)
(BTW, this front sight works extremely well and is very
visible in all lighting conditions)
-Check cylinder throats for proper size and uniformity
(Cylindersmith or done yourself if not uniform and/or proper
dimension); (Really matters if shooting cast)
