I see no reason why you're not allowed to take as many weapons out as a PC, follow my footsteps and take an AK12s and CMRs out on patrol... and get blacklisted.
i mean, you can say it, but it's out of roleplay, just dont rp giving out of roleplay stuff, just type it, you dont need to say "im passing you a note", it just mixes non rp with rp.

just hand the gun over? if im confronted in the hospital by police and have a gun, i just hand it over. When it comes down to it you're injured / recovering from injury and breaking the law, handing over your 200k gun isnt the end of the world.
