which model was that, Andy?Yep - it's so close, it's irritating; they could have just done it right first time around. I had to get a friend to mill 10-thou off the top of the slide, but it would have worked with 5-thou:
I put a dovetail front sight on & didn't have that problem (CS model), but it may have originally been staked rather than improperly dovetailed.
