The point of discussing the load of the striker is because that partially determines both the length and weight of the trigger pull. You can play with spring weights, add a 3.5 power disconnector to your Glock, but you're never going to get it as short or as light as a tuned SAO trigger. The trigger on the SAO doesn't have to pull back the hammer 40% of the way and release it. The disconnector weight on your Glock is not your pull weight. The standard disconnector is like 5.5 lbs but the pull ends up being a pound or so more. So you can add a 3.5 lb disconnector to your Glock and play with some spring weights, but it is really hard to get it much below 4.5 pounds. Actually more common on defensively carried firearms are the NY trigger modifications which add to the pull weight but make it a little more smooth so it ends up being like a 10 pound DA revolver trigger. I keep mine pretty stock. All I've done to my 10mm is add a stainless guide rod with a 20 lb spring. Even with the lighter trigger pulls though, we still have to acknowledge that the Glock is designed to be carried without a safety. It has striker blocks and drop safeties. Yes it will fire if the trigger is pulled, but probably not otherwise. Glocks have been dragged behind moving vehicles, shot out of cannons, and dropped out of airplanes to demonstrate this. The 1911 is designed to be carried with the safety engaged. Yes it has a grip safety in addition, but it still isn't as safe without the safety engaged as say, a Springfield XD. Because again, the XD is designed to be carried without a safety whereas the 1911 may not be, esp if it is an originally configured Series-70. Carry what you are confident in the way it was meant to be carried, but don't disregard an entire class of pistols based solely on the presence of a safety or whether it's safe for unsafe people. A safety is not difficult to master. It doesn't add time or complexity to the draw stroke. People are getting too caught up in the safety. If the pistol has a safety it is probably best you use it. If a pistol doesn't have a safety, that's fine too. Practice with what you got and be safe. Safety is a frame of mind, not a mechanical device.
