Definitely consider the Para LDA. It has a true double action trigger, so the issue of decocking it goes away. Very consistent and smooth trigger and pull force is not an issue. It will remind you of a revolver, except better. The firing pin is locked out unless you both pull the trigger and compress the grip safety, plus it has the standard thumb slide safety. It essentially cannot fire accidentally due to dropping the gun because the firing pin is disengaged when the gun is not gripped in your hand. Flip off the slide safety when you put the gun in hand and you are ready to shoot. The recent models have the power ejector, so the spent casings fly out high and to the right. It won’t eject weakly and into your face. With respect to durability, a Para .45 holds the record for most rounds fired with no jams. You can watch the video on the internet and see for yourself. Shoots a lot of different ammo due to ramp design, unlike some other .45s which are very picky, especially with hollow points. Avoid dirty ammo and clean the gun after each practice session and you will not have a problem. I like a product called Gun Butter to lube my Para. LDA comes in diffent sizes. You will want one of the compact models it sounds like. Para also has non-LDA models that are also worth considering.
please recommend me the best model in PARA LDA for ccw(but dont compromise long service life).i mean i can live with bit bigger size but not with small gun whhich is not durable.
