1911 Government Rear Sights?

[BoCash]

First of all, thank you all for a wonderful forum site.

I TRIED to post this on the 1911 forum but they sent a note I had to re-register due to no activity in a while and they were sending particulars to a dead email I can't access. DUMB!
I hate this modern electronic world!!!!!!!!!!!!!

I'm a former FFL (26 years) who began shooting and first gun ownership in 1957. Reloading for a large number of calibers and all gauges began in 1969. Now partially paralyzed, shooting and reloading are the main hobbies I can still physically enjoy.

Wanting to save wear and tear on some more collectable 1911'S, i've turned to some Tisas purchases.

I've purchased the following Tisas so far:

1911 Tanker (4 1/2") in .45.
1911 Service in .45
1911 Army in .45

All function wonderfully with the following tweeks needed:

On a sand bag fixed rest with target at 25 yards, the Tanker shoots to Point of Aim and is perfect. In fact, it is "crazy-accurate" for a shorter barreled 1911 in this price range.

However, both the Army and Service printed repeated groups at 3 inches low which is unacceptable to me.

I changed the rear sights of both of above to a higher .322" high basic fixed sight which looks appropriate to the model.

Now, Both of the above shoot 3 inches Higher than Point of Aim at 25 yards.

I don't know exact height of the factory rear sights of the latter two pistols but thinking they were about .200 to .210, give or take.

So question: Does anyone know of a source for basic rear sights that would be close in appearance to the basic original rear sights which might be in between
the original sight heights and .322" for the Service and Army models? I'm thinking .265 to .270 would be perfect. I've already exhausted personal searches.

Thanking you in advance, Bo in western NC

Perhaps filing the rear sight until rounds go where you want? Use caliper to check dimensions?

10-8 performance has or used to have some.

On fixed sights, often the problem is the ammo they are regulated for when made. On 1911A1 pistols during WW2, the regulation was always designed to be for GI 230 grain hardball. These days one doesn't know for sure what ammo a pistol is regulated for. You should try a variety of rounds in 230, 200, 185 grain weights to see where these guns shoot. You might get lucky and find one that shoots dead center. You may also find one that shoots noticably better than another.

One reason I put adjustable target sights on my 1911, different loads shot to different POIs with the POA of the fixed sights. More or less tolerable at 25 yards or less, but significant at greater distances. I was shooting Bullseye at the time at 25 and 50 yards. Mine was OK at 25, but I had to hold off quite a bit to keep in the black at 50 yards with fixed sights. For awhile, I was using different loads for 25 yards vs. 50, finally just put on target sights.

I always have adjustable sights installed on my 1911s, primarily for the much improved sight picture they offer. Makes accurate shooting much quicker.

I would put the original rear sights back on and file down the front sights a little at a time until you get the impact where you want it if were me.

Remington target 45 ACP ammo always shot about 3" low compared to other brands. Try other brands/other weights and see it that moves you POI.

You don't mention the ammo or load you're using.
But, if it's 230 gr hardball, consider leaving it as is.

Here's why:

When the 1911 first came out, you generally couldn't buy one. The government got them all. A lot of civilians got their first taste of one at the National Matches at Camp Perry.
You drew one from inventory for use in the match by luck of the draw. When done, you turned it back in. These were strictly "as issued" 1911s. No funny business. But, they were a lot better made than the later 1911a1 "rattle-traps"!
The National Match course was as follows:
-10 shots slow fire at 50 yds
-10 shots timed fire at 25 yds
-10 shots rapid fire at 25 yds
You had to shoot issue ammo, ie: 230 gr "hardball". There were no wadcutter loads.
If you are getting 3" high at 25 yds, that is perfect for a 6 O'Clock hold on the B-8 target.
At 50 yds, you use a center hold with the same load.

Think about it.
You might want to leave things just as they are!

Best Wishes.
Enjoy!

I agree, sounds like the sights are properly regulated for 230 grain ball ammo.
