I bought a set of these grips from John about 6 weeks ago. There was a problem with grips - a gap at the rear. After a couple of phone calls and a little further tweaking on my part, I sent them back to John, fearing that I might damage them. He returned them in about 10 days and they fit perfectly now. Laser works as advertised. He even threw in a second plastic adapter and battery pack.

John is a gentleman to deal with and stands behind his product.
