Converting model guns?

[Cheetah]

All model guns are made from zinc or some other metal that can't withstand the pressure of a round being fired. So it seems one would have to replace the entire barrel to convert it. Do you reckon any models might be more easily converted than others?

On another note, what handgun do you think is the most threatening, and realistic?

Define model gun.

Threatening? Probably a large revolver, or sawed-off. Realistic looking? I'd say a sig or glock knock off, even those bullshit .45's bb guns look pretty real. I dont know about anyone else but when a gun is pointed at my face I don't stare at the barrel to see if it's real. It's usualy a glance and when the guy sees that it's a gun they are either running or holding their hand up(like it will shield them hahah) and turning their head as far away as they can while still being able to see the guy.

You might as well get a real one, I buddy of mine had a horrible experience with a fake one once as a sort of drunken/high prank and it wasn't even a robbery type thing. You catch someone armed I can almost promise you they will flee just far enough to pull their shit out, then yer fucked.

By model I think he's talking about replicas though I thought those had no firing pins in them and other shit (or so I heard).

if im thinking of the same thing, you mean taking an air pistol and replacing the barrel and such to make it shoot real ammunition?

if so its a bad idea for a few reasons.
if the slide works on the air pistol, its usually made of aluminum and wont withstand the pressures of the blowback from a real bullet.

there is no ejection port for the spent casing go

no magazine

say in theory you did get one and you made it work, there would still be problems, strength of material i think would be the worst. also you would still have to buy all the parts to make it able to fire live rounds(springs, firing block/pin, barrel, guide rod, magazine catch, hammer assembly). to me it just doesnt seem worth the money or trouble.

try finding a "throwaway". they're extremely cheap not usually reliable but they would be moreso than if you made one from a bb gun

I think it's probably easier to build your own one than convert a model that's not designed to be used as a real gun.

If one would want to convert a model gun to "real" ammunition one should use .22lr or .22 short as these produce very little pressure.
There are comercial .22lr guns with magnesium cast frames and slides (walther .22lr target)
Some old cast iron capgun revolver can be converted to fire .22 short by the use of a drill press.

Also a better idea would be using a .22 barrel liner inside the converted guns barrel.

Expensive barrel liners at brownells (http://www.brownells.com/aspx/NS/store/catsearch.aspx?k=barrel%20liner&ps=10&si=True)


But a better idea is to get them from Numrich Gunparts corparation.

Rimfire Liner - .22 Caliber - Sweat-In Or Epoxy (http://www.e-gunparts.com/DisplayAd.asp?chrProductSKU=588180&chrSuperSKU=&MC=)

.22 Caliber Barrel Blank - Liner (http://www.e-gunparts.com/DisplayAd.asp?chrProductSKU=527760&chrSuperSKU=&MC=)

Chamber you barrel blank/liner with a proper .22lr/.22 short reamer or just use a 6mm drillbit.

By model guns, I mean "replica" guns, like these:

They've got pretty much everything, and the guns can even fire "blowback" rounds.

You could replace the barrel with a length of stainless steel tube of the right diameter for the bullet and reem it to the right chamber size. You wouldn't be able to fire semi automatic. You would have to restrict the slide's movement somehow and cock/eject manually.

The metal working would require a lathe, a bench grinder or dremel tool and a wire feed welder or a baby stick welder. It CAN be done, but the end produce will be an unreliable piece of shit. It would look pretty sick though.

One second thought, you might be able to make a .22 out of a 1911 model. Some quick calculations and research would give you the operating pressures. Find a round with the same pressure as the caps they use or slightly higher within a tolerance of about 5% and your golden. You might have to replace the firing pin/hammer with a real steel equivalent. Last I checked a 1911 hammer was 30$ +shipping.
