Frequently Asked Questions

Are your guns completely 100% English made shotguns?

Yes, every part of them including the barrels are made in house including our own engraving.

Are they true sidelocks or trigger plates (sometimes also referred to as 'boxlocks')

We make:
  • True sidelock guns o/u or sxs
  • Sideplated trigger plate mechanism o/u
  • Standard (square back) trigger plate mechanism o/u

What are the differences between Sidelocks, trigger plates and  'Sideplated' trigger plates ?

A true sidelock is a more sophisticated mechanism with many more components than a trigger plate, the 'trigger pull' in a true sidelock is often easier to adjust and is generally lighter to pull. 

A trigger plate has a much simpler mechanism and it therefore easier and quicker to manufacture. 

Sideplated trigger plates are trigger plates which are made to look like a 'true sidelock'

Where does your stock wood come from?

We use Turkish walnut and every piece is hand picked.

Who does your fitting?

A gun fit is included when you purchase one of our  'sidelock' guns or 'sideplated' trigger plate guns.  We do this all in house, during the manufacturing process you will be invited for a fitting when we check your measurements and how you mount the gun and we shape your stock to you while you wait and with your involvement.

Our 'square back' trigger plate guns come with standard stock dimensions or adjustable stocks although we can offer a customised stock as a cost option.

Can I choose my wood?

Yes, of course, we have around 700 pieces from which to choose.

Why do you advertise your guns as being the Worlds's most accurate ?

Because of our manufacturing methods which are both repeatable and reproducible (we machine from one solid piece of steel or titanium rather than fabricate from several seperate pieces).  According to ISO 5725-1, the general term "accuracy" is used to describe the closeness of a measurement to the true value.  The precision of a measurement system, related to reproducibility and repeatability  is the degree to which repeated measurements under unchanged conditions show the same results.
