 Adjustable Sights on a Combat 1911?

What are your guys thoughts on these?

I've had exactly 1 experience with adjustable sights on a gun. The sight flew off on a Springfield Loaded I owned. I've sworn off adjustable sights since then.

Is my experience indicative of the overall robustness of adjustable sights? Or are they strong enough for duty use now?

Prefer fixed sights on a "combat" handgun myself.

A good adjustable sight isn't going to magically get off. If you want a site that you can get dead on without have to deal with sight blades and using a pusher for drift then go quality adjustable.

I'm listening. Who makes a quality adjustable and what would you personally recommend?

I love my TRP Operator, but the one thing I didn't like was the adjustable sight. It's a good design and all, I just don't feel that adjustable sights belong on a combat-type pistol. I ditched the adjustable sight and put a fixed sight on it. Oh, and I should mention that the adjustable sight on my TRP had the front pin walk out after less than 100rds. I'm sure SA would have fixed it, but I lost confidence in it after that.

I think that's what happened to mine. I either didn't catch it in time or it happened real fast, but the whole rear sight came apart and flew everywhere during shooting.

Bo-Mar, Wilson Combat, & Nighthawk Custom make adjustable sights.

I wouldn't intentionally install them on a carry gun, but having had several 1911s with them, I wouldn't fret too much over carrying a gun with Bomars mounted on them.

Based on the millions of rounds and hours of shooting that competative "action or practical" (USPSA, or IDPA) shooters do, I've gleened that the WIlson Combat adjustables are perhaps the best, although, Bomar, STI, and Caspian are good too, and that they should work for you. Although they will eventual break. Read details on the Brian Enos shooting forums.

I've seen fixed sights fail too, although the rate should be somewhat better. The usual (and not infrequent) problem being that they fall out of the dovetail. It's happened to me three times with three different guns.

Didn't Bo-Mar close shop?

Yes. The owner and his son were in a fatal car accident last year and the surviving family members were apparently unable to come to a satisfactory deal with anyone to sell the company.

US manufacturers have begun to pick up the slack, with Strayer and Ed Brown, among others, making their in-house copies. Champion has been making Bo-mar clones overseas for years as well, and OEMing them to semi-custom makers in the US.

Regarding the Springfield adjustable sights and their hinge pins: this is a common issue with these sights. I also experienced the hinge pin working out of the sight on my 9mm. Staking the pin is a virtually permanent solution to this problem. Another less positive fix is to remove the pin, put a slight bend in it, and reinstall it.

My opinion is that a quality adjustable rear is fine for concealed carry. I wouldn't want one on a duty gun because they tend to get banged around more and collect more crud. Even if the rear sight goes haywire, your focus should be on the front sight anyway.

Personally I don't see a lot of need for adjustable sights. Just about every 1911 with fixed sights I've owned has shot close enough to POA that I've never felt the need for an adjustable rear.
