Fine Folks of Forum,
If you do shoot your modelguns, how do you secure the area?
Cartridges are usually ejected even up to 2-3m away, with quite a force, and they are heavy and tough.
A cartridge hitting an object will damage it - dent wood (floor or furniture), punch a hole in a plaster wall, scratch metallic or painted surfaces, make fall down or break up smaller objects.
If you can shoot outdoors, it is probably ideal sitation, but when having fun indoor one needs some preparations.
Floor should be covered with something soft, absorbing impact (even if cartridge just falls out of ejection port it can do damage) like carpet. Ideally there would be a soft "wall" (larger piece of material) to catch flying cartridges gently and bring them down in a controlled way to the floor.
As a minimum - make sure that along the axis of expected (sic!) cartridge flypath you have something on the floor: carpet, sofa, bed, to soften the impact. This doesn't take care of unexpected paths though.
Some replicas (machine guns rather than pistols) have shell catchers - this is useful, although it obscures the action.
Please note that different modelguns eject cartridges in different ways/directions: while most tend to eject in right&slightly up direction (MGC 1911, Berettas), some eject to the left&up (Marushin P-38), some upwards (Marushin M712, MGC Winchester 1873), some straight to the side (MGC Automag). Some even don't eject at all, and if those are revolvers, everything's fine!
Apart from cartridges one should also take care to not have anything flammable near barrel exit (for the models with open barrel) and chamber area, as hot gases can cause damage too. This is usually not a big issue, unless you experiment with magnesium.
There is also the noise. Modelguns have different loudness, ranging from a quiet click (Marushin P-38) that doesn't even disturb a small child in the same room, through repeated shots (full automatics) up to a loud bang (MGC 1911) that makes your ears ring if fired in a closed space (such as a room). I consider impact of noise on surroundings (am I going to scare someone in the flat? are neighbours sleeping already?) as part of security of this hobby - not making trouble.
Shooting a replica for the first time is more nervous, as you don't know yet exactly what to expect for noise and cartridge flying out (observe extractor/ejector placement).
What are your thought on this subject?
