Rolling a 1 on an attack with a pistol

[Coinshot Colton]

Say you have a pistol with the Greater Reliability enchantment, and you're a level 10 Gunslinger. If you roll a 1 on an attack, is it considered an automatic misfire? Or does it not misfire because the Greater Reliability enchantment gives it a misfire score of 0?

A misfire of 0 should mean you never misfire.
If they had intended 1's to always misfire I suspect all reduction abilities would have said "minimum 1".

Gunslinger: Reduce the misfire chance for one type of firearm by 1/4. You cannot reduce the misfire chance of a firearm below 1.

This special ability can only be placed on firearms. A greater reliable firearm is enchanted so as to be less likely to jam than other firearms. The greater reliable special ability reduces the misfire value of the affected firearm by 4 (minimum 0). This reduction occurs after any increases are calculated for firing with the broken condition, or for any other effect that might increase the misfire value of a firearm. A firearm with the greater reliable special ability cannot have the reliable special ability.

So it's possible that you do not experience a misfire even when rolling a 1. But take for instance a fire lance, not a popular weapon but does illustrate the point I'm about to make. It has a misfire chance of 1-4. Greater reliable would completely negate this. Now, if you read the description it's clear you can't use alchemical ammunition because the durn thing uses javelins as ammunition, but ignoring that let's assume you can. All alchemical cartridges increase the misfire range by at least 1. Which would mean your range would be 1-5, and greater reliable would reduce that to 1.

I guess my point is, just make sure to keep track of what your running total for misfire chance is and how the enchant negates it.
