With the experience I've had with Remington, parts will likely be needed. I've had two brand new 870's that were pure garbage. You'd definitely have more experience than me on the subject but I won't buy any Remington, post Freedom Group.

I’ve had zero issues with 20ga Remington stuff, so far. 12ga/rifle stuff, meh. For a turkey gun, there’s more parts, accessories, and options for the Remington, and more custom work available. Not knocking the Turkish Mossies and Weatherbies, because I’d try one with no reservations. Just is what it is on what you need. I’m more interested in the Turkish 28ga for rabbits.

Oh, I'm not saying they don't turn out some that aren't right.

I had a brand new 20 870 in this past weekend to drill and tap.

Owner had not even fired a round through it.

When I function checked it all was good until you pulled the trigger and held it while working the action then releasing the trigger. It wouldn't reset. The bolt lock arm was a few thou too long. It was an easy fix, but something that should have been caught before it left Remington. (Quickshot, if you are reading this, it wasn't yours ).

Having said that, I have had to work on quite a few Turkish shotguns for broke or incorrectly working parts. One was a Mossberg, others were Tri-Star, Charles Daly, etc.

If tss is going to be your thing, I'd find a quality pump gun and not a cheaper semi auto.
If you go the semi auto route, hold out for a Franchi or buy the Stoeger. I have not seen or heard of any issues with the two of those except that they don't feed the longer shells (roll crimped MOA, the XXXL, etc...)

I have heard of issues and witnessed issues with:

SA -08
Tri Star
Browning Silver
And a Remington 11-87 youth

Most of the time the "you get what you pay for" saying holds true from my experience. The last thing I want is a turkey gun I have to baby, or that I'm worried about not operating correctly when I get to patterning before the season, or worse yet not functioning properly when I'm hunting (much less on a trip half way across the country)

Advice:

Buy a tried and true make/model: the best at which fits in your predetermined budget.

Semi auto:
Benelli sets the bar IMO

Pump:
Lots to choose from here
870's come reasonable and tons of upgrades to be had.
Winchesters, Browning, Ithaca well made but heavy.
Mossberg has some cheaper no frills thumpers that kill on both ends.

I bought one for my oldest daughter when she was small. I never had any issues with it. Sold it later on to 257 I believe to make a lightweight turkey rig out of. They’re a decent starter gun. Not sure about longevity as I didn’t have that one real long
