I Do Next to Nothing to a Crosman SSP 250

As dedicated readers already know, I purchased a Crosman SSP 250 at a local garage sale for $15.00. It was missing a few important pieces, the loading gate, and the seals for each of the two barrels. Derrick managed to find a spare loading gate, seals for all three possible calibers, and a .20 cal. barrel. Total cost was a paltry $20.00. All I had to do was install the new loading gate and do some cleanup work as the pistol surprisingly had good seals.

The SSP 250. SSP stands for Silhouette Sports Pistol. The brass barrel is the .20 cal one, the .177 and .22 are both blued steel.

The barrel seals and new loading gate. The loading gate is prone to breakage.

The gas cap. It does not seal the end of the tube, the cartridge seals directly on the valve.

I started by loosening the allen screw in the breech (sorry, forgot to take a pic) and removed the front sight. The front sight is also missing a shroud, but it doesn't need it to function.

I slid the barrel out. The turned down section is so the sight screw can pass through the barrel housing.

The barrel band setscrew is loosened so that the barrel hosuing can be removed.

Two screws hold the forearm on.

One screw goes into a lug on the barrel band, the other a lug attached to the grip frame.

The rear sight and screw was removed.

Then the other screw which holds the breech onto the tube.

A standard Crosman transfer port.

The rear grip frame screw was loosened, allowing the hammer assembly to slide out.

The other grip frame screw was removed and the grip assembly removed. Note the standard tiny little safety spring that can pop out.

Again, a typical Crosman grip frame.

The side plate was removed. Both the hammer and sear were painted that odd shade of green.

All the parts were pulled out. Notice the small spring washer on the trigger pivot pin. Also note how filty the trigger is.

The only work I did (beside a quick cleaning, wire brush and steel wool derustifying and a slathering of cold blue on the tube and housing) was to polish the contact surfaces of the sear. I used the two machinists stones shown and stroked lengthwise. I also lubed that which needed lubing.

The pistol went back together and looks cleaner now. Another kind forum denizen pointed me to the manual which shows the procedure for swapping barrels.
The SSP 250 is fun to shoot! It will make a tin can dance. In .20 caliber I got between 400 and 440 feet per second, depending on how much gas was left in the cartridge.

Where can one buy a Loading gate for this pistol? And which of the seals require regular changes?

For reseal kits, parts and service you can try Bryan and Associates, Mac1, Precision Pellet or JG airguns.

Tell them we sent you.
You might as well get a reaseal kit if the pistol hasn't been shot in a few decades.
