This is everything I carry on a typical weekend (I don't usually carry my backup on weekdays)
Beretta 96D .40 with 3 mags (34 rounds total)
M&P .40c (backup) with one mag (11 rounds total)
2 pair Peerless handcuffs
OC-10 Pepper Spray
Surefire tactical flashlight
Gerber Tactical Knife (Don't often use this particular knife, usually I have a smaller, folding knife)
5 "C" cell maglight
A crapload of keys.
All of this, plus body armor ends, up weighing about 27 lbs. No wonder career cops have bad backs!
