Ok, I'll play ....
There aren't many american made shotguns anymore ...assembled maybe ...but american made - with american made parts, sadly, is becoming rare.
I guess it depends on what your measuring scale is ? For me the scales are determined as follows - by action type / I will say these guns are above average / not high end( call them an 8 out of 10):
1. Pump Guns- Browning BPS and Rem 870 Wingmaster ( not the Express,etc)
2. O/U -Browning & Beretta(field guns, target guns, etc-each have a level ..)
3. Semi-Autos - Beretta or Rem 1100 gas guns / Benelli inertia guns
In general, I think the Turkish made guns are below average / when compared to all 3 categories above. But its not a black and white issue / there is lots of grey areas ....but I'd put most Turkish made guns, based on what I see today between a 3 and a 5 on my scale.
Browning and Winchester are part of the same corp now ( FN ) - and mostly made by Miroku in Japan ......and I'll put them at an 8.
The Italian made guns - Beretta Intl ( Beretta, Benelli, Franchi, Stoeger ) .... I'll give Beretta and Benelli an 8 / Franchi a 6 or 7 / Stoeger a
5. Perazzi I'll give a 9 ....
German made .... Blaser I'll give a 9 / Krieghoff a 10...
American made .... Kolar I'd give a 10 ( but I think there are some German components in his guns / not sure ). Lujtic I'd give them a 9 ....
Russian made - Baikal ... I'd give them a 2 ...
Its only my opinion / based on the 25 or so shotguns that I own ( and in full disclosure / they are mostly Browning and Benelli - because they fit me / and they have held up to the test of time ) .....as well as what I see at the gun clubs I frequent, sporting clays shoots, registered Trap and Skeet shoots ....
Regardless of where a gun is made / often, I think you get what you pay for. Its not all about fancy wood. Sometimes it is fit and finish / but its also in the quality of the steel, springs, etc ... Too many shops sell virtually 100% based on price / especially the big box stores...with very little knowledge of bird hunting or clay target shooting.
I was in Cabelas on Tue / asked to see a nice Browning Trap gun for about $3,000 ( that I don't need ...) and the sales guy doesn't know me from anyone else ....and he says, sure its a nice gun / but he says he'd never pay that much for any gun ....and Cabelas bills itself as a "high end" sporting goods opeation. I didn't buy it .....I have 5 or 6 Browning Trap guns already ....just hanging out / looking ....but even they sell based on price vs .... "How much Trap do you shoot?", What is your dedicated Trap gun now ?, How long have you been shooting Trap ....or any number of 20 other things that might have helped him decide if I was a serious buyer for that gun / or even another more expensive Trap gun ...like a Krieghoff KX-5 or maybe a Lujtic ....
