Nothing wrong with Turkish shotguns, so long as it's understood they're disposable.
I have a few Turkish pumps, semi's and O/U's. Some of them appear to be well made, but comparing them to my "real steel" counterparts that they're based off of leaves a lot to be desired, especially in the actual use department.
I think the Turkish SG's have been great for the Canadian market, specifically, getting people into tactical shotguns who may never have went that route.
They have some good ideas too. They have/had a model that was an 870 clone with a 13'' barrel, with the receiver being made out of 7075 aluminum, and the stock sets being very, very nicely done (Turkish walnut) wood.
Comparing that to one of my Wingmasters with a 12" barrel (apples to apples) it's night and day. The clone obviously being worlds lighter. Despite that fact, it never did or will replace my 12" wing being my bush/camp SG of choice. Turkish firearms are budget alternatives, not replacements.
IMHO.
TLDR:
Turkish SG's; good, for short term. Interesting concepts, budget friendly.
