Since my earlier post on this thread, I purchased a S&W, M&P 340 Centennial. Took it to the range today and it appears I can handle Winchester, 110 gr. JHP self defense loads in it. (I don't think I'll be practicing much with them, (they do 'bite'), but 5 to 10 ronds at the end of a range session is ok.
The pistol is light, (13 ounces unloaded), small framed and has a tritium front night sight. If I chose to carry it in a front pocket, it would be just fine but I really prefer a strong side belt holster. Wearing a 'bowling shirt' or a T-shirt untucked, the gun is invisible!!
