I have a Contender carbine (16.5") .223. I bought it because it seemed to be handy. I do not like the stock. To me, it seems like one kind of has to "wear the stock" rather than use it. A thumb hole would not help, but IMHO, would slow down operating the hammer. Mine is fairly accurate, but I keep stealing the good scopes off it for some other use. I think it is now wearing a 30 year old El Paso Weaver. Plenty good for stuff in the pastures that need shooting. jack
