Assuming the enemy team has armor, FiveSeven would be best as it has good armor penetration, damage and bullet capacity. If you can hit them in the head and/or have little money, the P250 is your weapon. If you want to save up money, stick to USP/Glock and try to sit some off-angles/spots to shoot someone in the back. You can double HS someone with head armor with USP and kill them. Only buy the Deagle if you can use it. If you can use it correctly, it can be very useful and have a big impact. You need however two kills to make up for the cost. Lastly the CZ (alternative to FiveSeven) if you have good spray pattern (however little bullets there is in the clip) and good HS aim. Limited bullets tho.
