Sorry. Thought I had replied to this already.
I don't have glories, but if you post the details of the prayer piece, I'll go over it. If your primary concern is inflicting agg damage, either a 2 dot custom artifact or sorcery will do it. A 1m surcharge per shot basically just buys off the misc action to reload. Doing that for free would require either artifacts or spells as Inexhaustible Bolts of Solar Fire is pretty much beyond a non-archery focused starting character. A custom artifact or spell would do either, depending on which direction you want to go.
Gather's notion of a ECJ would also work well, with the limiting factor of Phantom Arrow Technique not working on firewand charges. You'd need to combine that with an artifact. Unfortunately, ECJ's are inherently destructive. Using one with a Holy effect may or may not work, and if it does, it will have unintended side effects. Translation: mad science.
On a more general note, where exactly are you going with this? Is the gun style weapon something you're interested in, or is it simply a combination of mechanics? Firewands do a lot of damage, mitigated by ammo costs and reload times/low rates. If stylistically you aren't after one, there are other weapons with do the job better and easier. If you are, something can be arranged, but you may wind up creating your own artifacts/spells. Translation: mad science.
