I just registered as so I can learn from those that have experience. I've owned various Rugers over the years and at this moment in time I'm trying to revive a Super Blackhawk square trigger guard model. I hope to connect with a gunsmith I was dealing with, about a cylinder he had. I did a BoBo and shared some contact information to get this part. I will be carful not to do that again. I am desperately hoping He may be on this forum too as he works on Rugers.
