You're welcome Elen, and I'll comment on some more of your pictures soon. Hey, maybe you can show a close-up of your pistols sometime, and say something about them? I'm not sure what you did to them exactly. Did you paint the black maybe, or the silver? PS: you should make sure to use the 'Reply' button for replying to someone, so they get notified by dA; otherwise they might not realize you replied. But luckily I spotted your reply anyway.
I forgot to press the "Reply", in any case, you're still reading my comment). Here's a [link] to a more detailed picture of pistols. And yes, they are different in their parameters - one mechanical and one gas. Also, the colors differ and I repainted them.
