I agree with the above posters. The .45 is a fat bullet to begin with, and so in lighter weights, can have penetration problems - the DPX is an exception because it uses a lower drag construction. Otherwise, I'd prefer a 230gr Gold Dot load, and the Double Taps, as always, do have some extra oomph. The Double Taps are actually very reasonably priced for premium ammo. Georgia Arms makes even less expensive Gold Dot loads. Speer is really the standard bearer in my mind, and I don't think you will ever go wrong with them.
