For those who might not know, the Swartz safety was an early attempt to make the basic 1911 pistol "safer." I'm fuzzy on the timeframe and exact mechanical details, but IIRC, it resembles the later Series 80 'enhancements.' Fortunately, it didn't catch on.
A sweet gun, but I personally feel that $12,500 is a bit much for it.

I imagine AX will weigh in on this with the details. I'm pretty sure that the Kimber "II" series all have the Swartz safeties (or a variation thereof), a concept similar to the Colt series 80 firing pin block. Had a friend with "II" series 4" Commander style Kimber (can't remember the model number). It stopped the gun from firing due to dirt/debris/powder fouling that caused the mechanism to stick.
FWIW,
Paul

Search posts by 1911tuner on the highroad.org IIRC he discussed it a bit, and he for sure knows the 1911 inside and out. His posts are a great resource for anyone interested in the 1911 and how to make them run right.
Unfortunate how that forum fell apart.

Johnny's a good man & does indeed know John Moses Browning's finest inside & out. I had the pleasure of attending one of his 1911 seminar/tutorials at his house a few years ago. Can't add anything more than has already been posted on that safety, tho I won't own a 1911 with a Series-80 or Swartz safety. JMB knew what he was doing, designed every part & every angle on the 1911 for a very good reason & when you start to deviate from that, yer gonna start having problems. |

The thing to understand is the swartz safety we see in many Kimber 1911s (Series II) runs off the grip safety. The Series 80 Colt type we see in 1911s, with firing pin safeties, runs off the trigger. They both do the same thing, namely they unlock the firing pin. Never had one fail but personally know very knowledgeable 1911 guys who have. One complicates the trigger and both can cause the gun to not fire. In my small mind bad things for carry guns and game guns. The one 1911 with a firing pin lock I keep is an old Officers Model I bought in the early 80s and traded to good a friend that returned to me a while back. A few years back an old buddy pulled out an early National Match Colt from the 1930s to show me the swartz safety in it. Pulled out the books and sure enough Colt did it first, almost 100 years ago.

I won’t have either one. I can tell you for a fact the Colt version will fail as I had a bad guy toss a Series 80 Colt Delta Elite out of his drivers side window during a pursuit. When it hit the pavement it went off. But truth be told, the pavement has always been hard on impact...

When it hit the pavement it went off. But truth be told, the pavement has always been hard on impact... ***** Fermin.... remember your mention of this caper. If the grip safety depressed on impact and inertia of the trigger caused it to trip the sear, the pistol could fire. Yet, inertia of the slide might fling it open, disengaging the disconnector. Some sequence of events enable the pistol to fire. By grinning chance, did the bullet strike the driver? The old pencil test: Unload 1911, drop eraser-end of pencil down barrel. Level pistol, pull trigger... watch pencil sail across the room. This launch pays witness to John Browning’s inertia firing pin. The long protrusion of the Browning firing pin insures ignition of primers which resist the firing pin strike of some other pistols, including SIG/Sauers and Glocks. Various examples of the Colt Series 80 failed to throw a pencil as far as the standard 1911 firing pin. Removing the firing pin from culprit Series 80 slides reveals peening marks on firing pin from striking the firing pin “safety” plunger. In other words, the plunger fails to clear the firing pin when the trigger is pulled. A trigger job and, especially, a trigger stop could aggravate the problem. A light INDENT (light primer strike) is another symptom of interference between the firing pin “safety” and firing pin. David Bradshaw |

Not the one I was chasing and thank goodness not me!
