I'm going to say No, the BH grip frames are not as friendly as the Colt is. The BH is bigger and bulkier to me. The BH does have a similar way of being a naturally good point and shoot feel and does have good ergonomics for reaching the hammer naturally but it does not feel as good as a Colt style. The BH is a "Tank", big, heavy, over built, can take anything you throw at it and the grip frame reflects that.
The new model Vaqaroes are much more similar to the Colts and feel like it in the hand.
Thank you. This is exactly what I wanted to know.
