Wow, thats a complete package deal! Where were those manufactured?
I finally got all the parts I needed to rebuild my Dad's 79G. I replaced all the seals and degreased and cleaned it up and got it back to tether with no issues. Some of the O rings were a real pain to get on, those little buggers can be stubborn! It's now shooting, but I an experiencing some leakage when it's fired. It feels like it blowing our just above the grips, which makes me thing it's the port between the chamber and the barrel. Like the Crosman setup, there were no seals here, just a metal to metal connection. Any tips on how to fix this seal would be helpful. Other than that it's shooting just fine and I'm excited I was able to get it back in service. Today, I'll spend a little time getting it sighted in!

Today, I'll spend a little time getting it sighted in!most likely the barrel isn't lined up with the transfer port. the single biggest problem I've found on the ones I've worked on. that, and the hole in the valve body is too small to allow the transfer port to properly seat in the valve. once you address those issues, you won't have any leaks coming from the barrel ever again.also, when you adjust the barrel, and re -tighten the barrel screw, ( the one on top, just forward of the breach ), make sure you don't over tighten it, or it will push the barrel out of alignment, causing the bolt to bind, or, refuse to close at all.
Awesome work Paul!Glad it worked out for you and your Dad would be happy you are enjoying it. I believe yours is hotter because of the Mac1 kit. I should have also said that I polished up the poppet shaft. Mine was a bit rough. I too noticed an increase in fps. Yours is very healthy. On another note, after getting a 78 and a 79, I also got Crosman MK I and a MK II. The MKs do have better triggers but I get 50% more shots per cart with the S&Ws at same power. Don't know if that's universally true but the shear number of shots per cart with my S&Ws amaze me.

Power is better too! I ran all three through the chrony with the Gamo Platinum PBA CHS pellets just to see what the maximum FPS was for each. The 79G is putting out way more! The only pistol I own that will better it is my 1377 with the steel breech kit and 25% larger transfer port.Pistol Platinum PBA Premium Hollow points79G 606.78 FPS 517.3 FPS2300S 541.44 FPS 467.52 FPS2240 510.02 FPS 477.14 FPS1377 672.14 FPS 580.90 FPS (10 Pumps)
I don't know if you can annodize pot metal. You could have it powder coated, though.

You could have it powder coated, though.Is it safe to do powder coating since it will require baking or heating after the coating is applied? My concern is, isn't there some sort of seal between the grip frame and the piece of metal where we screw in the piercing cap that may get damage by the heating process?
