As a matter of interest, I had two Model 10 air pistols re-sealed at the same time. Both were in excellent cosmetic condition and bought from two different sellers with the knowledge that they both needed re-sealing and fitting with new pairs of springs.

When they were returned one would shoot so high over the target that the sights could not be adjusted low enough to bring the shots back down onto the target .

The other Model 10 shot way underneath the target and did not have enough adjustment left on the rear sight to bring the shot back up to the target.

Without seeing this or experiencing it you wouldn't believe it!

Both Model 10's had been resealed and fitted with new springs and both shot well and with good power making it hard to understand what was going on at the time, but the gunsmith had not shot either pistol at a target after rebuilding them.

It was suggested by the gunsmith that the owner of the first pistol slammed the barrel shut hard enough to bend the barrel upwards over a period of time, and that the previous owner of the second pistol opened the barrel when loading too aggressively causing the barrel of that pistol to be bent in the opposite direction.

Both pistols looked OK and did not look like they had bent barrels.

Both were adjusted by leaning on the barrel in the right direction to correct the problem.

We had a Model 6 in the club once that shot so far to the right it could not be adjusted far enough to the left to bring it back on target. Armed with the experience gained with the soft barrels on those two Model 10 air pistols I gently pressed against the barrel of the Model 6 when it was rested on a wooden bench until I corrected it for the happy owner!

It is surprising just how soft the barrels are on these Original air pistols, how easily they can be distorted out of shape, and how easily they can be corrected!
