Tang locking screw on high grade guns

[Bill Murphy]

Some lock screws line up with the larger screw. Some are installed at a 90 degree angle. Which would be considered correct by a classic gunmaker like Purdey or Boss?

I think that in order to determine the correct alignment of the tang screw lock screw one has only to look at the lock screw’s alignment for the screw on the sides of the frame.


The lock screws I’ve seen on classic European guns share slot alignment with the action screw they lock.

Yes Dean, i would agree with that from a standpoint of logic. Every Parker was fitted with a lock screw on the hammers. And they are positoned at 90 degree angles from each other. And the very few examples I have seen on a lock on the tang screw, it is in the same fashion.
I would not expect Parker to deviate from the norm in a different area of the gun.

I do however think it would look better if both were in line with eachother.

What nobody likes the random untimed lock screws on John Browning's A5? I give it a pass since its not a double but I have to say it drives me a little crazy when most gun screws aren't properly timed. Might be a little OCD but I even try to time outlet cover screws in the house!

You're not alone Channing - I do exactly the same thing... throughout the house.

Lock screws aligned with the larger screw are not the easiest task to make perfect. I remember a Becker Fox pictured in the DGJ that I used as an example for my gunsmith, Mr. Vicknair, that I would not find acceptable. He came through with flying colors and made the screws not only perfectly sized and aligned, but almost invisible.
