Jason Harris - Gunsmith

Jason Harris, Gunsmith

At 15 years old, a week’s work experience at a local gunshop led Jason onto a Saturday job which evolved into his full-time career. Jason did a time-served apprenticeship; learning hands-on in the shop but also attending college to study mechanical engineering to HNC level.

Working in this environment was invaluable experience, not only for the skills learned, but also for meeting others in the gun world from whom he has learned so much more about guns and gunmaking.

Jason has carried these skills forward into his own business and maintains good relationships throughout the gun trade. Whilst he enjoys the contact with customers and being in the shop, working on guns and the workshop environment is his first love.

With over thirty years experience working in the British guntrade we are able to carry out a wide range of work and alterations to the highest standards. Whilst most of our repairs are carried out on the premises, we also employ the services and extensive knowledge of some of the best trained London craftsmen. Thus we are able to offer work to the same standard as many of the best London gunmakers.

We are capable of carrying out service, repair and restoration to guns of any age; though our specialist fields of knowledge cover the more modern style of guns; i.e. hammer and hammerless guns from the last half of the 19th century to date.

Whilst we are happy to give valuations after examining a particular gun, we regret we cannot give valuations online. We carry out a full range of stock alterations and fitting work to guns across the shotgun spectrum, be it the oldest hammer gun to the latest Beretta or Browning OU.

We can work to measurements supplied by a shooting school, or we are happy to advise on gunfitting and alter the gun accordingly. We are able to give an estimate, on request, for any work, but only on sight of the gun.

Below is a list of work examples that we can carry out;
