I would go with either the GLOCK or the XD. non ported models. If you plan on buying new ammo all the time and not reloading then I would go with the glock 22 great gun will not jam. I however wanted the option to reload and purchase ammo that had been reloaded. I also wanted to shoot lead bullets(glock does not recomend this). So I went with the XD and have not regreated it. The gun shoots great and feels really good in my hand. For more info on why not to reload the glock or purchase reloaded ammo check this web site.
