Not easy using jpa-g jpoint glock adapter base on a g43 - JP Enterprises JPoint Mount Adapters for Pistols

I experimented installing the JPA-G JPoint Adapter base on a Glock 43 to mount my Optima red dot sight. It worked fine, but I didn't like the base dovetail protruding from the slide. So I milled about .110" off each side to match the G43 slide width. What I didn't do was measure the taper of the dovetail before machining. MY BAD! If I had I would have found that it had .020" of taper from side to side, much more than the .008" of the Trijicon HD rear sight I removed. This clearance between the base and slide dovetails, on the right side of the slide, allowed the base to lift and tilt dramatically to the left. To remove this clearance I inserted two short lengths of .003" brass shim stock between the front and rear slide dovetail surfaces and base dovetail. Problem solved. I've since put a hundred rounds or so rounds through the 43 since mounting the red dot and noticed my accuracy is greatly improved over the Trijicon HDs, particularly at longer distances. Nothing is wrong with the HDs, my 70 year old eyes are the problem. How will it hold up, and maintain zero? Only time will tell. Last week I sent an email to JP Industries expressing my concern with their machining tolerance of the JPA-G base dovetail, and also suggesting they manufacture a base specifically for the G43. No word back yet.
