Its easy to make a single shooter with the apropriate tools
Its easy to make a revolver typ pistol if you have the right tools and some know how.
I dont think its too hard to convert a replica into a real thing if you have the tools and the knowhow. Probably easier if you get the parts somewhere online. Replicas already have a firring mechanism (most) and a magazine slot that works all you need to do is replace the barrel, or the safety system or both depending on the model. Most replicas just have a "welded" safety so you can technicaly never shoot it but everything else works and is identical to the real thing.
But since weapons are so controlled in the UK getting the bullets would be the hardest thing
