William, It should also be noted that older versions of the Springfield Mil-Spec 1911-A1 pistols have a trigger pull of around 7 pounds. If you do not want such a heavy trigger, than the newer models that have only a 4.5 trigger will be more to your liking; especially if you are interested in firing quickly and accurately. Installing a slightly heavier recoil spring is one of the best upgrades for your weapon. Try an 18 ½ vs the 16 that most Springfield Mil-Spec 1911-A1 45ACP pistols come with. The heavier spring offers a little more power when chambering a round. I would also replace the rear sight.

I always replace the titanium firing pin with a steel one for reliable ignition.
