I love my Sig P238 it is much more comfortable over my dads LCP and easier to control even with the pierce grip extension on the LCP. If you regularly carry a 1911 the P238 will be the perfect BUG. If you regularly carry something that doesn't have a thumb safety, then the LCP may be better as you will not have to get used to the P238 thumb safety.
If anyone is wanting to give the P238 a try I would be willing to meet someone at a range in my neck of the woods ( i.e. BV pistol, Lakeville Gander...) and let them give it a spin as long as you bring your own factory loads.
