a 100 year old pistol thats never changed...

[PT945]

And that would be the colt 1911 that went into service in March of 1911, and has never changed designs. Its one of the only pistols I can think of that has never changed.
There a is a semi truck load of upgrades and add on's. But the mechanics and design stay the same.

you can still buy a colt army...but it's a revolver....

how old's the high power?

[PT945]

What I ment was still in production with no modifications.
The hi power was made in 1914 but has had several changes made over time .
