The activation switch is excessively hard to activate, to the point of being uncomfortable !! the factory says, this is a known problem with this model of grip, no fix in the works, for $200 + dollars, id have to say it's a poorly engineered product and you may wish to try one before buying or look for another product !! too bad, I waited for 4 years for a laser to be produced for this pistol and after all that , it turns out to not be a very functional product !!
On point every time. Ordered wrong model and Crimson Trace was so courteous and fast with making it right. Made in the United States! Get one. Thank you Crimson Trace.
