I recently read online many folks stating the the PARA USA PDA 6+1 LDA  9mm and 45 auto used standard compact 1911 grips. That information is not correct. The PDA is a 6+1 round . This means the grip frame is too short, about 1/4″. The screw holes are not in the correct location and the grips are much thinner than a typicall 1911.

Further complicating matters the 9mm and 45 PDA are not the same either.

The only source I have found manufacturing grips that will fit either model Para PDA is Raasco Grips.
