I have a 7.45 LDA and a 6.45 LDA. Both have proven to be excellent performers. I have fired the 7.45 a great deal more than the 6.45 and it has been utterly reliable, extremely accurate and easy to shoot. The trigger is amazing. My experiences with the factory have been quite positive (they were quick, courteous and professional about fixing a problem that was not of their doing). I have used it in IDPA and it acquitted itself well, no failures of any kind (at least not on the gun's part!)
The 6.45 has also proven to be an excellent shooter, particularly for such a small gun. Also very accurate and reliable and suprisingly easy to control.
I have full faith in the LDA pistols and wouldn't (and haven't) hesitate to carry one with which to defend myself.
Good luck in your decision.
