The "holes" referred above are those stick-on things that look like bullet holes.
Such a sticker is generally circular. It is likely available with a peel-off backing. In this case we want the backing to be somewhat special. It should have a set of slices in it not unlike a pizza, with a small
circle in the very center removed.
The sticker is placed in the gun backing-side first, and bent so that the pre-removed circle is bulging toward the end of the barrel.
A blast of pressurized gas forces the sticker down the barrel. As it does, interaction with the air causes the rest of the backing to be peeled off. The sticker then flies free and when it lands, it sticks and a neat-looking and harmless bullet-hole appears. Short-range only, of course.
I recognize that the center of this special sticker may need to be given a bit of mass, to encourage it to retain what little aerodynamic shape it has, while flying through the air (looking mostly like a badminton shuttlecock, only smaller). If it hits a person, it might sting a bit.
Considerable design work may be necessary to make the gun multi-shot, but I see no major obstacle to such a possibility.
--Oh, and I forgot to mention the sound effects. We want it to be noisy, like a real gun!
(Hmmm...why is there not a "Product: Toy Gun" category?)
Not perfectly round, but perhaps close enough

why not exactly like pizza? |

I think in the 70s there was a movie SFX multi-barrelled gun that shot glitter and glue balls to simulate bullet holes on glass/mirrors.

Is there any other kind? |

[po], one intent of pre-bending the sticker, being put into the gun, is to just start the peeling process. But pointy ends at the center would tend to prevent air from getting under them, and lifting/peeling the pieces of the backing off (unless the pre-bending was more extreme than I've been imagining). With a small central piece missing, air can more easily get at the edges surrounding that piece. I forgot to say in the main text that the stickum should be very light-duty, not too different from note-pad sticky's, to ensure the backing does peel off easily. |

[coprocephalous], the word "shuttlecock" by itself does not necessarily automatically and quickly bring to mind an image, to people who haven't played with them in many years (I had actually forgotten the name and had to look it up), but the additional word "badminton" solves that problem (which in my case made looking up the other word easy). |

(+) Since this is the bakery, I will forego the "toy guns that look real are a bad idea" lecture. |

These would be great. The hoodlums and
gangs have gone mad in Hartford,
shooting one another like crazy. |

I read somewhere that the special-effects way to put "bullet holes" on glass was to put a glob of Vaseline and some black threads into a gelatin capsule, and fire it from an air gun. I tried that (with a slingshot) on my car window, and was pleased with the results. |

There was the baseball shuttlecock, but it was discontinued in 1927 as it made for a slower-paced game and was incongruent with the game's name. |
|
| |
The shotput shuttlecock only lasted one year in the 1908 Olympics. |

Each hole is very slippery on the outer face. Thus it does not stick to the one adjacent in the stack. |
|

I wonder if one had a wire rim to compel a circular form, if one could shoot these to fly as a horizontal spinning disc. On impacting a wall, perhaps it would turn to lie flat. This would work better with double sticky holes. Which would be harder to keep in a magazine. |

Sounds like a low-lethality HESH round. |
|
| |
When a HESH round impacts a target it deforms into a pad, after which the base-mounted initiator triggers; the concept is that this detaches a "scab" of armour from the inside of the vehicle, causing alarm and despondency amongst the occupants. |

Wadcutter ammunition, used by competition pistol marksmen, is a pure cylinder; the intention is to avoid "keyholing" in targets, where the projecile impacts at an angle, producing a deformed outline and possibly lowering the score. |

Something resembling a wine bottle cork, with suffiient mass to allow it to fly "true" from a weapon resembling a paintball gun. Since paintball guns are smoothbored, helical grooves on the projectile's sidewall will be required to impart rotation to the projectile to stabilise it in flight. |
|
| |
At the base, an obturating disc to contain the propellan gas, or a structure similar to a Minie ball (q.v.). |
|
| |
At the head, the adhesive disc, and a friable or collapsible support, capable of supporting the adhesive during acceleration and flight, but deforming predictably on contact with the target, analgous to a HESH round, applying a "pancake" of adhesive material with an appropriate colouration. |
