Really good versatile home primary home defense shotgunReview by Ken
I recently purchased a Tristar Tec-12 shotgun from RedDotArms. I took the shotgun to the range yesterday. I put 20 rds of #6 2.75" shells and a half dozen #7.5 through her and three rifled slugs at the 100yd range. The Tristar is different sounding. Can't really tell you what to compare it too, but it has a distinctive sound you will remember

The manual says not to run "Heavy" loads in pump mode, and that their might be issues with "Light" loads in semi-automatic. I am a new shotgun gun guy, and I found no definition of Light and Heavy loads in the manual. I am assuming it means 3" shells for Heavy loads, and maybe like 7.5 or 8 for 2.75" shells? In any case, I only had 2.75" with me. It worked fine in semi-auto just fine for all the birdshot, and I didn't try the slugs in pump mode.

The sights were dead on. It's harder to follow through with clays with it. But I really am liking the sights. Last point, you really need to clean this before taking it out, as it comes with a heavy coating of oil. It seems reasonably well made with quality parts where it counts. I do like the option of semi-auto or pump a lot. I think this is a quality shotgun with a lot of features and you'd expect to pay way more for it. An Excellent value.

Firearms Policy

How to Buy a Firearm or Ammunition

Federal firearms laws prevent the sale of a weapon from Red Dot Arms, LLC. directly to an individual in another state (we are located in Illinois). We must ship your firearm directly to an FFL Dealer near you. The steps to follow are:

  1. Order your firearm online using our secure shopping cart. If you know the FFL dealer you are going to use at time of order placement (not a requirement) enter his name and address into the 'Ship To' field.
  2. Find an FFL dealer near you that will accept the transfer of the firearm for you. Most sporting goods stores and pawn shops will provide this service for a small fee. Also, gun clubs, shooting ranges, etc. may provide this service to you. If you don't know which FFL dealer to use in your area, put a comment in your order and we will help you locate one near you. We have access to a large list of dealers in the USA that will gladly handle a transfer for you. Most dealers charge around $25 for a transfer. You must confirm the transfer with your local FFL dealer in advance.
  3. Next, have the dealer send us a copy of his signed license if we don't already have it on file. To check whether a license is on file, contact us. Please Note: It is now legal for us to accept a faxed or e-mailed copy of your dealers license! 
  4. Make sure the dealer knows the firearm is coming from Red Dot Arms. If you used a dealer that we already have on file, call him to let him know that a gun for you is on the way.
  5. We will send you an email when the firearm ships, which will include a tracking number.
