Don't stop here, it looks not really good but it can be fixed.
First, why use a heightmap when you can use a normal map?
Heightmaps are for displacement, a gun like this doesn't need displacement if modeled correctly.
Secondly, The bump is WAY TOO MUCH. Come on now, this looks like metal done in the middle ages with an anvil and a hammer.
No actually, it doesn't even look like metal. WTF did you do? Is your metalness map grey or something - it needs to be white, this is metal.
Did you even look at references?
You wear and tear looks completely random and arbitrary, the wood looks like leather and all those little things come together and make the whole gun look like crap and very amateurish.
Find reference photos of old and used colts and actually fucking look at them.
Don't wing it, be diligent and observe how it actually looks like then replicate details you see precisely.
