i have a new P12.45 LDA.
it doesn't shoot to where the sights point, but it does shoot quite reasonable groups. the windage should be no problem at all to correct since the rear sight is in a dovetail. it's shooting quite a bit low, which will be a bit harder to fix
in any event, it's pretty easy to adjust the sight picture & shoot plenty well.
i have only shot a few hundred rounds through it so far. so far it has worked perfectly with ball & hydrashocks. it really doesn't like SWC bullets, though.
before i tried the trigger, i imagined that it might be heavy. however, i was totally amazed at how light it actually is. it's quite a bit lighter than a smith target trigger on a double action revolver. i think you'll have to try one to believe it. i certainly wouldn't want mine lightened at all.
it is pretty hefty compared to most guns that people carry.
IMO the p12.45 LDA is a wonderful pistol. i love 1911's, but for carry, i prefer the 12.45 LDA especially because of the double action trigger and the small size.
