I usually have OC off duty. It only makes sense to have some intermediate force available. For that, I carry Sabre pepper spray, stream configuration. Been hit with the cone stuff by my co-workers too many times to have an appreciation for it.
I prefer my 2.9 oz can of Sabre "Phantom" OC at work, but it's a bit much for daily carry. Good for dog walking though. A friend of mine busted his can of Sabre yesterday. That stuff is the gift that keeps on giving. He's still wiping OC off his belt, holder, etc. and cursing every time he touches his eyes. I've laughed alot today, at his expense.
