There have been a couple of "solutions" to the "carrying-cocked-and-locked problem." The LDA was one. The other was the safe-fire system developed by Bill Laughridge of Cylinder and Slide (see:
Safety Fast Shooting Kit). With this device, the gun is carried hammer down, round in the chamber, and the thumb safety engaged. But, when you flick the thumb safety down, the hammer rebounds and cocks and the gun is ready to fire (condition zero), so you've got the same sweet short single-action pull without having the carry the gun with the hammer cocked, which apparently scares the daylights out of non-dedicated personnel.
I can understand why some LE administrators and the military freak at the idea of cocked and locked carry. After all, John Browning had to add the grip safety because of concerns that too many soldiers would suffer ADs without one, even with the thumb safety.
But, for a civilian or an LEO well-schooled in the manual of arms associated with this pistol, and a gunsmith checked and worked piece (you really want to make sure that it requires
positive pressure to disengage the thumb safety), I don't see the problem (excepting of course the PR problem in LE applications). Cocked and locked is how the gun was designed to be carried, and I feel utterly safe doing so, especially with a good rigid OWB holster that covers the trigger guard.
I have shot the LDA and it really is an amazing device. Who would thunk it that the engineers could have designed such a short, light DA pull? My problem with all double-stack Paras is that I have very small hands, and I can't get on the trigger properly with a double-stack .45 -- the grip is just too chunky for me. For others though--like LEOs who want a .45 on the 1911 platform but who would never get permission to carry cocked and locked--the LDA may be just the ticket.
Anyone here actually own a Cylinder & Slide converted 1911 with the SFS modification? I understand that they also make a kit for installing the same system on the P35.
