Ah, yes, iron sights

Nope. That's the second rear sight blade that's broken on that gun. It's a Wilson, no MIM parts. Adjustable rear sights on 1911s aren't all that strong.
Wow. I have a BoMar like that. Gun (caspian) is easily 20-30 years old

How many rounds have you put through it? This was my USPSA and IDPA competition gun. I put thousands of rounds through it. I'm not sure if that sight blade is Bomar or Dawson.

I bought it used. Probably 4K by me. I have not shot it in 6-9 years.

So what do you do now? If it’s the second failure, do you replace the slide? Can you do anything to the channel the sight sits in? Put in a fixed sight?

I have 1911s but none of them are near that round count.

Replace the slide? Um, no. The problem isn't the slide.

This is simply a known issue with Bomar-style adjustable rear sights on 1911s. The rear portion of the sight blade is relatively large and heavy. The slide moves backwards and forwards relatively violently. The sight blade material is relatively thin and eventually metal fatigue results in it breaking. So I replace the sight blade.

This is a game gun. I do not recommend these style of rear sights for defensive purposes.

Thanks - I'd not seen of or heard of this before. 1 of my 1911s with Bomar sights sits at about 1K. Looks like it's not something I have to worry about yet, but should be aware of.

Same here. True Bo-Mar adjustable rear mated to Dawson fiber front atop a Caspian 1911 custom built for me about 20 or more years ago. It was also my primary competition pistol for many years in USPSA & IDPA. Many thousands of rounds down the pipe with nary a hiccup that I couldn't blame on my damn reloader. 🤔🫣🤐🙄

I gotta get after that guy....
 
1911 competition gun 20,000 ish rounds thorough it. Front sight broke where it over hangs the dovetail. Dawson stood behind their product and sent a replacement

Military 1911s had fixed sights, not an adjustable rear sight. It's the adjustable ones that break.

I did not know of this issue. Now you have me concerned with my Kimber Target 10mm with the same adjustable rear sight. My Target model has a 6" slide , not sure if this is better or worse for putting recoil stresses into the rear sight.

It will likely eventually fail if you shoot it enough. But that’s a game gun, not a defensive gun.

Ah so you one of those guys (single stack) that cause all the traffic jam at the stages… serves you well that your rear sight fell of.

I joke, I joke… :p
 
I'm not a 1911 guy so I don't understand. What's the point of putting these quick adjust windage rear sights on a handgun? Are people really determining... Hol up.. wind quarter value from east to west, lemme get my Leatherman and fix up my sight first before taking that long range shot with a 45

They get a last minute chance to zero before their duel at 20 paces.

Some handguns are mechanically capable of amazing accuracy, I think 2" at 25y is often achieved, sometimes even 1". Think about that, Fixed combat sights won't work for aiming such a handgun to that level of accuracy. They need the adjustability, as well as the smaller notch of the rear sight matched with a narrow front sight.

For a lot of precision “bullseye” competitions, the 1911 is king.

They are meant for target shooting, not defensive. Particularly if you are doing something like bullseye shooting where you want a very accurate zero. Its quite hard to get a truly accurate zero if you can only adjust windage with a hammer and punch, and can only adjust elevation by swapping front sights.
