Well made upgraded spring. Works very well better than stock spring. Fast shipping

Cherry on the pie

Adding these springs completed the upgrade for my P11. Along with the trigger, the trigger spring kit, the stainless guide rod, and the 12 round magazine, this pistol is now fully complete and I am confident carrying this pistol every day. Don't misunderstand, my P11 was good right out of the box, however these upgrades tend to validate this weapon. It is a super sweet shooter, and really didn't cost to much, or take too long to upgrade with M*CARBO.


I replaced the trigger, trigger springs and guide rod in my p11 and considered each modification to be a considerable upgrade. However I was not pleased with the recoil spring kit. After reassembling the firearm with the new max control recoil springs, I could feel the coils dragging on the bottom of the barrel when working the slide by hand. The binding was severe enough that it was difficult to get the slide back far enough to lock the slide and remove the slide pin. I fired the gun and wasn’t too surprised that it malfunctioned after just a few shots. I noticed that the new spring had more side to side movement on the guide rod than the original spring and Upon measuring the outside diameter of the outer spring, found it to be .010 larger than the original. Also noticed that unlike the original spring set the new inner and outer springs were wound in the same direction allowing them to overlap and go farther off center on the guide rod which I believe added to the clearance problems I was having. I changed back to my original springs and have no more issues.
