How has the Tristar worked? That is one I been looking at also
My son likes it. One thing however is that the spring that goes around the magazine tube broke and had to order a knew one.
Like all gas autoloader. Just make sure you clean it regularly.
I can see how that spring and mag tube could be an issue if you don't clean it regularly and keep it properly lubed/oiled. I was surprised that it didn't have a big spring in the butt stock like a lot of other auto loaders. The butt stock is completely hollow with only a giant 10" lag bolt to screw into the back of the chamber.
The issue is that the gas ports are on the barrel (like every other gas auto I've taken apart) but because the spring and charging limbs are on the mag tube, the recoil spring also gets carbon build up as does the mag tube.
So if you let it go too long w/o cleaning the spring and charging bars, the gun won't cycle smoothly and get gritty with carbon build up. When that happened, the spring coiled over itself and broke. (Think like a slinky when the coils get all kiddy wampus. Only this being a metal spring causing it to break.)
Now, Tristar sent a new one and arrived 2 weeks later just in time for our youth turkey season.
I also have a Youth Tristar 20ga that has the 2 inch extender to go from a 24in to 26in barrel and it also has the youth and adult stock. So it can grow with my kids.
I tried the 20ga spring for a temporary solution until the .410 spring got to me. No dice. The two springs appear identical in size and number of revolutions of coil. But the 20ga spring wouldn't allow the chamber to come fully open nor lock open. My guess is the spring tension on the 20ga is more ft./lbs than the 410. Which would make perfect sense since 20s kick more than 410s.
All that being said, it's a fine gun.
We got it because it's an autoloader, .410 and it's about the lightest kicking option for my kids. Not a lot of other options other than single shots and pumps.
I also got a limb saver recoil pad for my kids, I had to take it to a gunsmith for a grind to fit pad and he also had to drill some new holes because no other butt pad manufacturer has the correct holes for the youth stock. I also put a 2nd bead on it so my kids could line up the sights properly. That was until my brother bought them a red-dot site and we popped that on. Much to my distaste. I'd rather then learn a bead since that's what they'll eventually get to for other bird hunting excursions.
