KiT reçu aussitôt monté!
Excellent, sur mon SIG SAUER 1911/22 depuis son acquisition cette arme me plaît énormément mais elle me posait quelques problèmes au niveau de l’approvisionnement, de la percussions et chose importante arrosait beaucoup par rapport au bushing de centrage qui a énormément de jeu sur le canon de ce fait la culasse ne se repositionne jamais au même endroit cela a pour inconvénient une grande imprécision de ce pistolet. Montage du kit complet, ce n’est plus du tout la même arme, aucun défaut de percussion ni d’approvisionnement, et grosse amélioration au niveau du groupement ! Ce kit n’est pas bon marché mais franchement je ne regrette pas mon investissement, je recommande vivement cette transfo pour pouvoir utiliser votre arme avec tout le plaisir que procure un 1911!

GSG/SIG Grandmaster kit
Followed all instructions to upgrade. Trigger is much lighter and handles well except for one thing it fire's the first shot the second shot fails seems like the hammer strike is too light when you pull back the hammer and fire the round it goes off and the rest of the magazine cycle's.It never fails 10 magazines gone through and the same result 2nd bullet doesn't fire every time other than that all good no jams no feeding problems just got to pull back the hammer after the first shot ?

Grand Master Indeed!
Installed this kit to fullly revamp my ATI 1911 22, I used this for primarily SCSA Steel Challenge Matches. This kit did not disappoint, install was simple and fit perfectly. Took the stock pistol from shoot semi sloppy 3-4 inch groups at 30yrd to 1-2 moa groups! That accurizing cone and bushing makes a tremendous impact on accuracy in a postive way! However I would have liked to see this kit come with the ejector and extractor upgrades included instead of the trigger tuning kit. If youre skilled with the 1911 platform you can make 90% stock springs work for you and get an incredible trigger with proper forming. Thank you ZRT TACTICAL!!
