problem with elif?

[Osires]

Okay, so this is a snippet of my code (the very beginning of it) that I have isolated in a separate file because it is dysfunctional. We are supposed to create a zombie survival game, but in this code here whenever you input anything other than "spas", it loops back to start (aka "Choose weapon: "). I've been fighting with this for a long time and now I've given up. I don't know what to do. I'm new to Python so please forgive the mess, I just need to know why my elif is just completely disregarded. I'm using Python 2.7.13

crowbar = 'crowbar' and 'Crowbar' and 'crow bar' and 'Crow bar' and 'Crow Bar' and 'bar' and 'Bar'
spas = "Spas 12" and "spas 12" and "spas12" and "Spas" and "Spas12" and "spas"
glock = "glock" and "glock 17" and "glock17" and "Glock" and "Glock 17" and "Glock17"


for turn in range(100):
    weapon = raw_input("Choose weapon: ")
    if weapon == spas:
        weapon == "Spas 12"
        print ('You chose the Spas 12.')
        print ("\n-----------------------------------------------------------\n")
        for turn in range(100):
            name = raw_input("\nNow, what is your name? ")
            if (not name.strip()):
                print ("\nPlease enter your name.")
                name = raw_input("\nNow, what is your name? ")
            if (name.strip()):
                yesno = raw_input("\nOh, so your name is %s? Type \'yes\' or \'no\'. " % name.title())
                if yesno in ["yes", "Yes", "y", "Y"]:
                    print ("")
                    print ("\n-----------------------------------------------------------\n")
                    break
                elif yesno in ["No", "no", "n", "N"]:
                    print ("\nHmm, that\'s not your name?")
                else:
                    print ("\nPlease enter your name and confirm it with yes or no.")
            else:
                print ("\nHmm, that\'s not your name?")
        print ("You turn around. To your left is a gun shop, and to your right is a hospital. Keep in mind you just got into a car crash, but you never know what could be out there. Choose wisely, %s." % name.title())   
        break
    elif weapon == glock:
            weapon == "Glock 17"
            print ("You chose the Glock 17")
            print ("\n-----------------------------------------------------------\n")
            for turn in range(100):
                name = raw_input("\nNow, what is your name? ")
