Pact of The Trigger

Warlock Level 3

You gain proficiency in Firearms.
Pact Handgun: You can use your action to summon a pact weapon in your empty hand. Your pact weapons can be used as your casting focus, so you do not need a free hand to cast spells. It is initially a small handgun designed in a fashion akin to your patron. It's normal bullets deal 1d8 magical piercing, it doesn't need to reload and has infinite ammo. It has the properties: Semi-Auto: -2, Light, & Compact. When making attacks with ANY Pact Gun, you add your Spellcasting Modifier to your hit roll.
Extra Attacks Starting at level 5 whenever you make a spell attack roll, you can also make an attack with your pact gun(this includes attacks from the pact gun). The amount of times this can be done per round increases by 1 at levels 11 & 17.
Your pact gun disappears if it is more than 5 feet away from you for 1 minute or more. It also disappears if you use this feature again, if you dismiss the weapon (no action required), or if you die.
You can transform one firearm into another pact gun by performing a special ritual while you hold the weapon. If it wasn't already, the weapon is now magical and it retains all of its regular properties and keywords.
You perform the ritual over the course of 1 hour, which can be done during a short rest.
You can then dismiss the weapon, shunting it into an extradimensional space, and now you can choose between that weapon and the handgun whenever you create your pact weapon thereafter. You can't affect an artifact or a sentient weapon in this way. The weapon ceases being your pact weapon if you die, if you perform the 1-hour ritual on a different weapon, or if you use a 1-hour ritual to break your bond to it. The weapon appears at your feet if it is in the extradimensional space when the bond breaks.
