I'm looking to throw an optic on my C.O.R.E. 5". I don't really want to spend the $$ on the RMR at this point and have been looking a lot at the JPoint. Has anyone mounted a JPoint on their CORE (or other handguns)? What would you suggest? Most web site reviews thus far are pretty decent. A person can pick one up from Optics Planet for $222 which includes a 10% off coupon for fathers day and free shipping...pretty darn tempting. Let me know what you think. Thanks
