View Full Version : why can't your typical Adjustible Rear Sight be "snag-less" w/smoothed out exterior?

First off, how much will you ever need to slide the rear sight L or R? Less than 1mm I'd assume.

Glock ain't too bad, at least both F & R sights are sloped all around.

But many handguns have a thin flat piece of steel at 90' just strong enough not to bend easily, but too thin to allow for rounding of its sharp edge profile.

Here is typical modern auto, any reason the rear face of the rear sight couldn't be sloped forward about 45'?http://www.smith-wesson.com/webapp/wcs/stores/servlet/Product4_750001_750051_770022_-1_757956_757781_757781_ProductDisplayErrorView_Y#

Here is typical DA revolver, the rear sight doesn't protrude far above the rest of the gun, but what does is 'sharp' and can snag on material or hands, and doesn't seem very well protected.http://www.ruger.com/products/gp100/specSheets/1748.html Couldn't the rear sight be moved 3/8" forward and nice rounded snag-less 'fenders' be added?

I'm also convinced that a DA/SA hammer spur could be designed with a spur that provides the same thumb ergo-metrics and same mechanical action, but includes a curved extension to prevent snagging when in the normal "hammer down" position and being drawn from a coat pocket. Might need to create a recess in the butt for the extension, but I'm seeing it as possible without interfering with thumb/index web.

Funny that you ask this. Someone at S&W decades ago thought the same thing you did, and they came up with this:

They make sights like the rear sight on the M&P so you can operate the slide without the use of your other hand. If your arm/hand becomes immobile then you need something you can operate the slide on. A table is an example.
Also, here is an adjustable sight that Sig sauer offers that is "sloped" http://www.sigsauer.com/CatalogProductDetails/1911-stx.aspx


Your hammer suggestion has been done for a very long time. Check out the S&W 669 or 469.

And even that can be sloped a good 20' or better.

I see "great minds think alike" on that old S&W, but I'd have the slopes reversed to better prevent not just snags but "hang ups" while drawing, and to better rack slide one handed. Of course it still has a snag prone hammer.

For the hammer I'm thinking of, it was for a revolver.

That Sig 1911 rear sight is sloped, but has alot of daylight at the rear. I'd want something totally flush at the rear, because that is where snagging happens. I'm not so worried about snags when holstering, but I still don't see why they need that much daylight so unprotected in any case.

I'd also want the rear most part of the rear sight totally solid, because it would be the first part hit if gun is dropped, because it is the 'outer most edge'.

I still think 'fenders' about 1mm or bit less on either side of rear sight, or totally integrated smoothed out R-sight would be way to go. Might need to have anti-glare finish.

Oh ok, I read your post wrong. Sorry, I get what you are saying now. You want the rear of the sight to be sloped to keep the gun from snagging. :facepalm:(to myself)

I have never seen an adjustable rear sight that is sloped in the manor that you suggest. Neat idea though.

I think SA TRP with rail is designed to use an adjustable sight but have it less "snag prone." But it is not sloped.

two very small bumps facing forward, neither of which look good for one-handed slide rack engagement points.

I do realize there might be certain minor advantages to a conventional rear sight, especially as it is used 99.9% of the time at a range.

You mean something like this?

This is the rear sight on my SIG 220 that is completely snag free and yet the slide can be racked one-handed

You could always install a DAK hammer,

but I like the hammer spur because it helped secure it in my duty holster (Safariland SLS)
