Just passing along information for others should they choose to install a light / laser on their EZ .380. I'm mid-60's with less than superman eyesight. Been installing some form of laser or laser / light combo on my pistols and really like what they offer. I do use the irons 99% of the time so the lasers are for a just in case scenario. My 9mm Shield sports a Viridian.
Anyway, I installed a Crimson Trace CMR-204 today on the EZ and used the #3 insert. Feels rock solid and will shoot it soon. Needed an OWB holster with this combination so ordered a Black Rhino Concealment TCSL. Not here yet but the one for my CZ P07 has been quite frankly the ticket so far. Hope this proves helpful to somebody. Good luck!
