So I'm fairly new to the SW revolver world. I've had Sigs/CZ75, but the opportunity arose to get a decent deal on a 629-4, so I jumped at it.

My CZ is polished SS with coco bolo grips and I wanted the SW to go with the same theme, so I go online and purchase. As you can see below, the stock code is SB so I'm assuming the gun is a square butt. Put new hogue coco bolos on (gorgeous btw), notice gap, begin researching, end up here.

Anyone help explain? Also, looking at my serial number, codes, etc...can you tell me anything more about the gun? Mid 90's I believe.

Thanks in advance.
