hood off the breech face

I have a barrel and the hood is .005-.006 off the breech face, as measured with
feeler gauges..

Is it safe to shoot? Will it cause damage to other areas of the pistol?

The hood end to breech face when the barrel is forced as far forward as possible is best to be minimum, however more is safe and will function just fine.

Youíll be fine. Iíve measured some OEM guns with as much as 0.017. Itís not uncommon to see them around 0.010Ē.

1911 barrel hood fit.....

I purchase after market barrels, and have used Kart, KKM, and Bar-Sto barrels over the years. When fitting the barrel to the slide, I like the length of the barrel hood to lightly touch the breech face of the slide, and the sides of the hood are a slightly snug but not a tight fit and properly centered in the slide. Once the gun is fired repeatedly the barrel hood fit will no longer be a snug fit but will mesh better in the slide. Most all of my well used 1911 or STI 2011 guns still have a good hood to slide fit, and when I hold the slide with the barrel in the locking lugs and against the breech face up to a light, you can not see any light around the hood fit to the slide, nor twist the barrel to see light around the hood.....IMHO, a properly fitted barrel and the barrel hood fit in the slide is just one part of producing an accurate shooting gun.

The last half dozen new Colts I've checked have had more than .020" loose breech. Guess that's what Colt thinks is proper fitting nowadays.

I've got 2 Springfield Armory 45 acp guns whose original barrels had gaps of .022" and .023". They functioned fine.

Optimal 1911 hood fit....

When the end of the barrel hood has an excessive gap to the breech face, I will weld up the hood to achieve less gap, and prefer the hood length to allow slightly touching the breech at full lock up, or within .001"

Even though the end of a barrel hood may have a wide gap at the breech, it may still function fine, but it may not provide optimal accuracy and may contribute to more wear and tear on the gun.... I shot NRA Bullseye for 12 years many years ago when I lived in the Tampa Bay area, and have owned quite a few Bullseye guns. I have owned a Giles, Shockey, and Clark (made by Jim Senior), and all of the barrel hoods were a very close fit to the breech, with minimal side clearance on the sides of the hood to the slide...… When I found a very good deal on a Bullseye gun made by a top gunsmith, I would buy the gun if it was in good shape, hold on to it, then re-sell it for a better price. I found a very nice Giles gun in a pawn shop in Tampa and a Clark accurized 1911 .45acp and paid $300 at another Tampa pawn shop..... I made some nice profit on these guns.....

Some 1911s have barrel hoods that never touch the breach face. The back of the barrel does all it needs to off the block to the left. Well almost all ways left block. If this is the case you could remove the barrel hood and every thing would still be fine. Many stock colts and usgi 1911s are like this. Not optimal in my opinion but still that case for lots of 1911s.

If your hood is short measure to make sure you have good case support while the 1911 is fired and that you don't have too much barrel movement forward and rear so the top lugs don't take a beating while the gun is fired.

Optimal barrel hood fit......

I am a DIY gunsmith and competition action pistol shooter. I build all of my guns for competition, and have built many 1911 and STI 2011guns and purchase aftermarket frames and parts for my gun builds.

I always purchase "gunsmith fit" barrels that are oversized in the lower lug area and the hood, to allow removing metal to make a proper fit. I also like to use W/N ramped barrels since they usually offer better case support. However, I have welded up the back of the barrel hoods and the lower lugs on a few of my used gun purchases, which allowed a much better fit and greatly improved the accuracy......
