I just got reminded. Would installing a BHSS SFS device help prevent discharge when dropped?

Probably not. It won't change the fact that the firing pin is free to move under inertia and is not physically blocked by anything other than the strength of the firing pin spring.

BHSS mentioned how the system was a good fit for early BHPs without firing pin blocks. You might want to look at the BHSS website for the 70s 1911 version of SFS. I am not a professional; I am just trying to list points here. I want your thoughts on this after you have checked the SFS device. BTW, there are SFS videos on Youtube; I thought there was one on 1911.

I remember something on the description of the SFS, it adds a layer of drop safety to early BHPs without a firing pin block.

I am familiar with the SFS. It has been around in one form or another for years.

The SFS modification replaces the pistol's hammer and thumb safety components and allows the hammer to be lowered and the pistol to be carried "uncocked." The hammer can then be "cocked" by sweeping off the thumb safety.

Carrying hammer down may help make the pistol more safe in the event that it is dropped and the sear or hammer contacts are somehow damaged which may cause the hammer to fall. But the SFS does not block the firing pin from its free movement and a pistol so outfitted would still fire if dropped muzzle down from a sufficient height.

I see; thank you for the explanation, sir.

"the sear or hammer contacts are somehow damaged, which may cause the hammer to fall." Can you elaborate on this? Didn't get you exactly.

Wayne Dobbs. retired law enforcement officer and now one of the Aimpoint sales managers, posted this on another forum:


"I've experienced, first hand, a drop fire from a 1911 and BillSWPA has some relevant advice that should be followed if you carry a 1911 or similar system with no firing pin safety.

My experience was with a 70 Series Government Model. I was running full out to my squad to respond to an officer needs help call. I was on a tile over concrete floor in the parking garage/basement level of a bank building and the thumb break on the holster was unsnapped. The firing pin was the stock steel unit and the firing pin spring was worn. Said blaster flipped out of the holster and went about six feet high (eye witnessed by another officer behind me) than came down on the muzzle and lit a round off, which fragmented and blew up some IR controlled glass doors in front of me. The impact was right beside my left foot and it's amazing I didn't catch some fragments. I caught a one day suspension for said transgression.

I'm a fan of firing pin safeties on duty pistols and if you're going to carry a 1911 without one, I'd strongly suggest a lighter firing pin (Springfield uses 9mm units) and keep a fresh extra power firing pin spring on the gun. (Keep your holster secured, too) "
