G24 Glock slides are scarcer than hens teeth. I just bought another one on ebay. I already have a new frame and a custom tight chambered .40 barrel so I don't have to play switch up between the .357 Sig and the .40. In these barrels the .357 Sig shoots a 125gr bonded bullet 1515fps and the .40 gains nearly 150fps over a standard .40. That puts these guns in the 600 to 700 foot pound range safely and they are super accurate. The primary use of these guns is hogs and deer and they work great in that capacity. Obviously I always need another hunting handgun.
