Crosman's Benjamin Trail NP air pistol

When I first discovered the "Benjamin Trail NP" nitro piston break barrel air pistol I bought it the next day!

Since I am in Canada, the detuned 495 fps version was all that was available.
The American version has a muzzle velocity above 600 fps.
Even still, a pistol that shoots lead pellets over 400 fps accurately can be alot of fun and useful.
My Benjamin trail NP has never shot close to 495 fps, and a leaky breach is the reason for this.
The seal sits too low and half the air blows out the breach when the gun is fired.

The solution is a new breach seal and special metal washers that the seal sits on to make an airtight breach.

D&L Airguns in Langley, B.C are sending me new seals and washers in the next few weeks, and I will update this blog with my progress.

Update: I replaced the breach seal and stuffed some Plummers tape under the seal to raise it up a bit.
The results are better, but I'll need to fiddle with it to get better results.
