I'm going to echo Silver Rings.
I got my TTn 78 back in Oct.
I called Walt and had it shipped to my FFL dealer ( he (the dealer) like it so well he order another after seeing mine , it sold the next day)
Out of the box , mine was well ! superb ( I asked Walt to choose one with a nice figured stock ) he did just that. Americam Black walnut , fit and finish is very nice and blueing is very well done.
My FFL still has the Russian Remington he had orderd just before my gun came in.
The gun comes with a spare set of hammer springs and a larger bead sight.
The distance between the triggers is just 5/8 of a inch. so thumbing both back at he same time is a breeze.
My gun already had the big bead sight installed, and so far the springs are just fine ( I have not installed the provided softer springs ) for my thumb.
The chambers need nothing "nada" ( unlike my Stoeger) no polishing at all to shuck shells smartly. I got love that ,I had to polish the Stoeger and de-burr the extractor out of the box, before the hulls would slide out.
As for shooting, I use AA light #8 with Clean shot.
However, for testing pattern out of the box, I had some factory Federal Field & Target 7 1/2 @ 30' both barrels (using a glow-see target)
were 10" ( a few shot pellets out at 12" ) mostly tight and just slightly bias up and left of dead on.
They list for $450 ,but I paid less than $410 shipped.
