This week, I received my USFA Birdshead hammer back from David Clements after he installed the rimfire firing pin. I gotta say, David did a truly remarkable job on it and I could not be
more pleased! Nonetheless, when it came time to reassembling the SA revolver, I noticed that the newly installed rimfire firing pin was ever so slighty
not perfectly aligned with my revolver's firing pin hole in the back of the gun's frame.
Mind you, Mr. Clements had the OEM slab-side 12/22 rimfire hammer to reference when determining precisely where and at what angle to drill the hole into the Birdshead hammer's face for the rimfire configuration. The fact that after receiving the hammer back from him, the firing pin didn't perfectly align itself into the frame's hole is not
indicative of any lack of skill on Mr. Clement's part. IMHO, he would have had to be "inhuman" to have nailed it perfectly the first time, the precision tolerances/dimensions and hole alignment are simply that precise with the hammer's firing pin.
So. . . to fix the situation I simply got out my trusty jeweler's metal files and small diameter dremel grinding bit and my dremel, and every-so-slightly and slowly and carefully
, removed material from the frame's beveled firing pin hole (while periodically checking for fit and rub/contact points of the firing pin to the frame). . . until I achieved perfection! Prior to filing and grinding the frame's firing pin hole, the Birdshead hammer's firing pin was making contact with the bottom portion of the frame's hole. The left and right side of the firing pin's alignment were perfect.
Anyway, the point I'm striving to make is, Mr. Clements performed the rimfire firing pin relocation and installation as humanly perfect as possible, without having my USFA Model 12/22 revolver to refer to. Again, I could not be more pleased with his execution of the hammer's modification.
Without further discussion, below are photos of my reassembled USFA Model 12/22 with the Birdshead hammer installed:
Here's a close up side view of the Birdshead hammer cocked in the 3rd position (i.e., fully cocked), for those that may be interesed in seeing how much clearance exists between the hammer's spur and the revolver's back strap/grip:

After getting the revolver completely back together again and manipulating the Birdshead hammer. . . I absolutely, positively could not be more thrilled with the gun's ergonomics and comfort!!! No BS!
For me, this custom modification was completely worth every penny. I know that for years to come a small grin of pleasure will momentarily wash across my face when I fire the first few rounds from my USFA Model 12/22 revolver each and every time, out at my local firing range.
