How long will it take me to find the starting weapons I don't choose?

Question

Before your first mission after the opening mission, I'm given the choice of four weapons:

• Stun Gun
• Tranquilizer Rifle
• Combat Rifle
• Revolver

One factor I'm considering is how long it will take my to find the weapons I do not choose, since ideally I would like to get my hands on them all at some point.

How long into the game am I able to retrieve each of these weapons?

Answer 1

The combat rifle is probably the easiest to get to. Almost every soldier, even at the start, will carry one.

A revolver is also carried by some soldiers, but less frequently, so I would put that on number two. It still won't take too long into the game though.

The first I've seen a stun gun was also somewhere in the early game, when I started for pacifist.

Seeing as I've had a tranquillizer rifle from the start, I've never bothered to look for one, but they are also present quite a bit in the first few missions.

To sum up, I don't think you'll have to wait long for any of the weapons, but the ones for up close are going to take a bit longer than the ones with distance.

Answer 2

• Stungun - You can find one after completing the first mission. It's in a an storage locker locked in an alleyway near Jensen's apartment. A hacking level of two is required to open it.
• Tranq - There are a couple of storage lockers in Detroit, also see the arms dealers.
• Combat Rifle - Soldiers and better armed gang members. Also look in your apartment for a few.
• Revolver - Some soldiers at the Milwaukee Junction factory may have them. I know they are found in Highland Park for sure though. (thanks @Arda Xi).
