S&W 79G/79G
« on: November 18, 2016, 11:16:14 AM »
I picked these up a few months back and stripped them down to replace all the seals and give them a good clean. All of the seals other than the valve stem face are orings that are easily sourced and replaced, the valve stem face is a hard flat seal which I ended up sending off to Wingman to rebuild for me.

From a bit of reading these pistols were made as a training version of the S&W model 41 and was produced between 1970 - 1978 before the tooling was sold to Daisy who reproduced a lower quality version of them. The 78G is .22 caliber and is known to be as accurate if not more than the original rimfire model 41 while the 79G is .177 and is almost as accurate as the 78G.

I haven't had a chance to chrony the 78G yet as it is still in pieces but the 79G was reassembled yesterday and chronied at 570fps with the JSB Exact RS without any adjusting of the HST yet which is set around half (done via a screw at the muzzle). A few shots on my range at 10m proved the 79G is very accurate and an absolute pleasure to shoot! The 78G I have is the dual cocking position model so you can shoot on high or low power without the need for any adjustments, Im hoping to get the it back together over the weekend to see how it shoots, I might even smooth out the co2 flow and open the TP up etc as I have heard these can be good for up to 9fpe which is heaps of power for a co2 pistol!

If you ever get the chance to pick one of these up I highly recommend it! They are a real sweet shooter and even the Daisy ones perform fairly well.

I had a full day pistol shooting on Friday. The 78G is incredibly LOUD compared to my other two pistols. I`m sure a dog two blocks away would start barking every time I shot it.
one trick with mine is to cock it before piercing the CO2 cap, otherwise it spits out gas. I store it with a full 12g cap in it at all times.

Sounds like your valve spring may be on the weak side, or maybe the valve seal is on its way out. They are loud but soo much fun!

Picked up a Daisy 790 last week for a bit of a project I have in mind. I want to see what the max power I can get out of one of these on co2 is, my prior experience with sody shows that the heavier the pellet the more time the co2 has to expand to its full potential so with that in mind I have decided I want to convert this to .25. Check out the mods section for a thread on that project. In the mean time here is a pic of the 790.
