Re: Suggestions on gloves for LE use?
+1 on the Mechanix gloves. I like the older M-Pact Stealth and the newer Impact Pro.
The Mechanix Tire Changer series are also pretty good. You get better protection (heavier fingers/palm, kevlar knuckle, longer cuff), but you give up some dexterity and they don't have the "stealth" colors. They also seem to have longer fingers.
However, if you're using them to search people with nasty stuff on them, or who are bleeding, or... Most of these gloves are porous and absorbent - so they can let nasty stuff through them and/or absorb to hold the nasty stuff against you. IMHO, nitrile gloves block stuff from getting on you, are disposable, and fairly puncture resistant -- in medical grade exam or surgical quality. They seem to slide better than latex, don't have the allergy issues, and seem tougher. They don't stretch as well as latex, so the size is important (the surgical ones seem to fit truer to size - but this may not be true for all brands).
Your local ER/hospital that does surgery should have some to try. A nearby coroner's office will have thicker ones.
