Inglis High Power malfunction

[us019255]

I took my Inglis High Power out of the safe for the first time in a decade. At the range I had a couple of malfunctions.

3 or 4 times while firing 200 shots, the hammer fell to the half cock notch instead of all the way. One way to clear this malfunction was to cock the hammer, and cycle the safety. Just recocking did not clear the malfunction.

My assumption is that even though the pistol looks quite clean, there is some crud in the hammer - sear mechanism. I will be detail stripping, cleaning and reassembling when I get a chance.

Does anyone have some words of wisdom?

Perhaps your hammer spring need replacement. Other than that how old is the gun, what series? You may need to replace a sear...I wish I had it a bit closer to examine. I even have one here to compare.

Your first idea has some merit, a bit of soaking, brushing, air pressure, and oil can cure a host of ills. Look also to the weakness or out of place-ness of the sear spring.

I was thinking of the sear spring too, it's that big flat one inside the mag housing. You may be able to give it some temporary power by giving it a bit of a bend. That would confirm whether it's that or not. Then you replace it. Johnny's probably right.

Worn rear knib on the Arm Connecting Sear

You mean the pointing down thing on the little long part? That pushes on the sear?

these were all made in 44-45 , mine have functioned fine every time without fail , i would think clean, possibly spring are worth checking , sounds like the safty is the issue ?

Thanks for all the advice. If a complete cleaning does not do the job I will look into springs. I have already suspected that the sear spring could be weak. I doubt that the problem is worn parts, but obviously will carefully inspect during the detail strip. This particular piece is one of those that came to the USA from New Zealand. I paid the premium price for one that appears to have spent 40+ years in an armory without being issued.
