Big902, +1 for what ming said. I have medium sized hands...don't like full size guns, and I love my grip size on the CBOB. You can even replace the grips with some of Sarge's slim grips to thin it out even more.
For those of you who commented on my slide lock problems... I spoke with a very helpful gentlelman at Dan Wesson. He said that sometimes that mags need to be tuned(?). He agreed with my assessment that the follower was just slipping by the slide catch sometimes. He suggested just slightly tweaking the upper right hand side of the magazine lip to accommodate a slightly tighter push against the catch. I'll let you know how it works. From what I've read these Checkmate mags and followers are supposed to be good.
