Mark has a point.
The McKinley Tariff of 1890 set the average ad valorem tariff rate for imports into the United States at 48.4%.
“Sporting, breech-loading double-barrel shotguns” had a 35% ad valorem PLUS an import duty of $1.50 if priced less than $6; $4 if $6 - $12; and $6 if priced greater than $12. “Single-barrel breech-loading shot-guns” had the same 35% ad valorem PLUS an import duty of $1.
“Forged rough shotgun barrels” i.e. non-joined tubes, however, were exempted which allowed the US makers to continue to import damascus tubes from (mostly) Belgium to fit and finish here.
The Tariff contributed to the Panic of 1893 with 500 bank closures, the bankruptcy of over 15,000 businesses, and the failures of the Philadelphia and Reading, Northern Pacific, Union Pacific, and the Atchison, Topeka & Santa Fe Railroads. An estimated 18% of the workforce was unemployed at the Panic's peak, especially in the west and in farm states as the price of wheat and cotton fell. A series of strikes followed in 1894, the worse being the Bituminous Coal Miners’ and Pullman strikes. The U.S. economy, and U.S. gunmakers, did not recover until 1896.
There was also a major push by U.S. makers (esp. Parker and Hunter Arms) to promote their guns for trap, and by the editor of Sporting Life Will Park
Feb. 16, 1895 Sporting Life (Spelling is as written)
During the past three years on visits to such sporting clubs as Larchmont, Carteret, Tuxedo and Riverton, we have noted the peculiar fact that out of 20 or 30 guns on the grounds at one time there will possibly be one gun of American manufacture. All the others are “Crown Grade Grenier's,” “Premier Quality Scott's,” “Purdy's” and other foreign makes.
The remarkable state of affairs, which is not creditable to American manufacturers, would indicate that there is something lacking on their part. We know that men with “hobbies” are willing to spend much money to gratify their “hobby;” but we are not willing to concede, if only from a patriotic sense, that American manufacturers are unable to satisfy their countrymen's “hobby” in guns.

“Some Facts About the Retail Gun Trade - The Mania For Foreign-Made Guns”
Parker Bros., of Meriden, Conn., are producing a Special high grade pigeon gun which is certainly equal to an imported gun in every way, and best of all, the shooting quality is not lacking.
The Hunter Arms Co., of Fulton, N. Y., also make a special gun which is finely finished, perfectly balanced and contains the best workmanship.
The Lefever Arms Co., of Syracuse are also catering to this better class of trade, and have already filled many orders for guns costing $300 to $400 which were equal in material, finish design of engraving and general workmanship to any foreign gun costing much more money.
