Help. Am I inept or what?. I ordered a Hogue Big Butt grip for my 625, and it arrived today sans directions. I thought this was because it would be intuitively obvious how to install them, but it turns out that's not true. The grips are cut to a very tight tolerance. The revolver's round butt will, with some resistance, go in about 3/4ths of the way and then hang up. I'm suspecting that the threaded u-shaped piece at the bottom of the grip isn't aligning up right, but there seems to be no way to wiggle it into place. My natural inclination is to force things, and I'm trying to resist that. Any hints on how to get this thing on without breaking it? Thanks
