Wheellocks and Flintlocks

[Sindri]

There's been a lot of discussion on wheellocks, I suppose no one can think of any factors to distinguish the different types of flintlocks besides the snaplock weakness to rain?

Why lower HP?

If the wealthy want more expensive guns they'll just get more decorations. In near-modern times this manifests in items such as Sadaam Hussein's gold-plated AK-47.

Only breaking more easily is a real problem. Costing more is an advantage when you're trying to distinguish yourself and more maintenance is a mild downside but also discourages their use with the sort of person who doesn't have servants. Also, unlike a gold-plated version of a regular firearm a wheellock requires different training which also helps to distinguish the wielder. While there's a lot of not-gauche things you can do with the exterior an intrinsically more expensive lock mechanism allows you to invest more in the weapon while maintaining good taste.

If spiral ("watch") springs had existing, wheel lock mechanisms would be simpler and might well be as reliable as flintlocks. If coil springs had been a little easier to make, you'd might see locks where you generated friction by pulling pieces linearly past each other. If somebody discovers appropriate metals early, modern cigarette lighter "flint" mechanisms are essentially wheel locks but with something that strikes sparks so much easier you don't *need* a strong spring to get the required forces. There are several chemicals that will work in percussion caps, and nothing about the roll of paper tape mechanism in a modern cap pistol toy wouldn't have worked instead of individual percussion caps. A slightly earlier discovery of batteries, piezoelectric crystals, any number of hypergolic chemical mixtures, or compression heating fire pistons could've sent gunlock development off in entirely different directions. An alternate history doesn't particularly need to have the same kinds of gunlocks as European history.

This is a good point. What are the technological prerequisites and other effects of having spiral springs or piezoelectric crystals?
