I think Cocked and Locked too dangerous for my tastes, consider hammer down safer, once the hammer is down. Never lower the hammer with a thumb, the pinch method is better.
I consider this tantamount to suicide
this is more controlled
So, if you understand I want a 1911 with a big hammer spur, don't want a long "extended" safety that is easily bumped to fire. And I don't want the modern beavertail that blocks access to the hammer. In other words, I am looking for a "Mil Spec" 1911. (I do want better sights and a throated barrel, GI 1911's have awful sights) I do appreciate short triggers because I have stumpy fingers.
In terms of "bang for the buck" I think the Springfield Armory Mil Spec the best deal. I have two stainless versions:
They are both accurate and reliable and shoot to point of aim with 230 grain bullets traveling at "GI" velocities of 800 fps.
I removed the proprietary titanium firing pins from all my SA Mil Spec pistols. These lightweight firing pins were installed so the pistols could pass a three foot California drop test. Titanium firing pins are also a known source of misfires in 1911's, so I removed mine and installed Ed Brown steel firing pins. I want an ignition system that provides the maximum amount of energy it can, to the firing pin and the primer. I am of the opinion that reducing the energy output of a firearm ignition system is a misfire waiting to happen. A weak mainspring will also creating timing issues with the slide. (the slide has to push the hammer down...) You can see how much titanium SA removed from their firing pin, in order to lighten it. This also makes installing a titanium firing pin a total pain as the sharp edges catch on the firing pin hole. I regularly clean out the firing pin hole and remove crud from the firing pin.
Just installed four steel GI firing pins in four Tisas 1911's. Tisas has installed GI configuration titanium firing pins, while I did not weigh the titanium, the GI firing pins went from 67 grs to 73 grains. Heavier is better for ignition reliability. Do understand the series 70 is not drop safe, either with a titanium firing pin, or a steel firing pin. It does take more drop height for a titanium firing pin to ignite a primer.
Just an opinion, but I have had less problems with fixed sights than adjustable. I have had pins come out of Bomar's, screws get loose. Had a number of times where sight base screws and elevation screws worked themselves out on S&W revolvers.
I went to the local gunstore and asked to pick the tightest and best trigger pull out of three SA 1911's which was a shock to the salesman. I guess I am not the normal customer as I consider these issues when buying. The new stainless I picked is as tight an my Kimber Clackamus and my Les Baer, and it shoots well. The used, 2012 SA Mil Spec, was as tight as a vault and had a great trigger. The hook was baited and I swallowed it.! Springfield Armory told me they make their own barrels. SA has its own forge shop, so the slides are forged, probably the frames. I don't like the reduced weight firing pin, but was able to find a steel replacement that brought the weight up. I think I have very decent, American made 1911's for the price.
