Nearly drop in upgrade kit for a SIG C3 1911
I ordered this kit, in conjunction with the one piece guide rod 25C for my SIG C3 Talo edition. Absolutely fantastic drop in upgrade it for the firearm but there were two points to be aware of. The C3 is a bit of a Frankenstein gun, with a Commander slide on an officers frame. So the sear spring needs a slight adjustment due to the shorter grip. When first installed my grip safety was inoperative, using some pliers i put a little more bend in the arm that presses on the grip safety, and function was restored. Likewise, the kit comes with a full size main spring for normal commander models. This will not fit in an officer size main spring housing. You will want to order spring P745CS-18 to complete the install. Aside from the sear spring modification, the rest is a strait forward drop in affair. Looking forward to range testing the gun with the new parts, seat of the pants improvement is slight, as the SIG trigger was already excellent. a WC sear and disconnecter are next on the list of upgrades.
