from The Century Dictionary and Cyclopedia
- n. A gun with an adjustable stock, used by some manufacturers of sporting arms to determine by trial the exact length and shape of stock which a purchaser may desire.
Sorry, no etymologies found.
A few years ago I had a full-scale fitting done by instructor Gil Ash. We used a try-gun, with a stock that adjusts in every direction, and we began with me pointing the gun at objects on the far wall of the Briley Manufacturing showroom while Ash tinkered with the stock.
Ash had me mount and shoot a try-gun, a shotgun with a stock that adjusts for pitch, cast, drop, and length, over and over again while he made minute modifications.
The best, costliest remedy is a formal session with a fit expert and a try-gun, which has a jointed, infinitely adjustable stock.
