The commonly available modelguns today are generally classified into display-only (or dummy / non-ignition) and cap-firing (or ignition) versions. Relatively there are far fewer "dummy" models than the "ignition" models in the market. Most dummy versions still highly replicate the appearance and internal mechanism of real counterparts with all moving parts work such that chamber / cycling dummy shells and field striping like real ones. The cap-firing modelguns besides highly replicate the appearance and internal mechanism as real guns like the dummy version, they are also able to "fire" the cartridge to produce spark, smoke, bang sound and slide cycling action (blowback) on automatic models.
