[quote=“EditorRUS, post:40, topic:4570”]the very first ones he can’t even fire because he have not … switched off (?) the fuse.[/quote] Do you mean the “safety” switch? The switch that keeps it from firing so you don’t accidentally shoot the wrong thing? English translation issue I assume 
The thing about identifying objects is that some people love it, while some hate it. The supporting side said it would add excitement to discover new items, help varying game-play instead of choosing the best statistical item in every games. The against side said it encourage metagaming, harder for new players while veterans would found out about it already, and involve having spoilers. NetHack is a prime example of this identify sub-game.
Personally, I’m leaning toward the first side, not a truly identify game like in NetHack but I’d like to see numbers get screened out or abstracted and slowly revealed as the character progress in relevant skills.
It could get partially done, sure. You’d just redact all the important information until the player makes a big discovery.
“A handgun” becomes “A pistol” when you stand next to it. If your character has decent firearms skill they’ll figure out brand and caliber (though since its stamped on all production guns it would be hard to argue that not instantly being revealed for everyone).
Stats, without decent skill, would be cluelessly blank. Fire it a few times, “Whoa, that has a kick to it”, game fills in recoil stat. Actually HIT something a couple times and notice it 1-shots a zombie at medium range … “Damn that is powerful” … damage stat fills in.
Yeah there is still the issue where seasoned players or those familiar with firearms would be able to know if A is better than B super fast. The only way I know of to stop that is either completely randomize weapon stats so a MP5 has varying stats each game (which would drive many people crazy if the gun didn’t perform as its real-world counterpart every game) or to strip all real-world names off the guns and THEN randomize it, because then you couldn’t get previous argument because who knows what a “Hetchin’Peckler 108” is SUPPOSED to perform like since its fictional.
Slightly off topic, but since you mentioned metagaming -> I pondered, what if character gained “familiarity” with a firearm as they used it, a specific firearm I mean. So on day 2 you find a Glock 19 and you don’t find another gun for a week. This whole time you’ve run every round you found through that 19, and even made some more by hand. Then you find what looks to be a more powerful handgun … do you swap out for the bigger model, or keep your old 19 because you’ve built up firing experience with it and it actually performs better for you now because you’re so handy with it. Sooner or later you’ve named your gun and wouldn’t put it down if you had to. lol
