Just completed working on a nice little home defense shotgun for a customer, which was the result of the review and modification work I completed on my own Weatherby SA-459.
Although the work was basically identical to my previous post, I thought it worthy of sharing since this project may help someone out there find a great option from the fairly limited selection of 20 gauge semi-automatic home defense shotguns that are available today. Weatherby certainly tapped a market that has been overlooked for some time.
Design characteristics of the 12 and 20 gauge are identical. To review, the most notable features of the TR model are an 18.5″ barrel, 5+1 stock capacity, ghost ring sight, and interchangeable choke capability. Out of the box the firearm comes with a cylinder bore extended-ported choke installed, which is ideal for home defense. Still a major purchasing factor for me, the optional chokes offer a more versatile shotgun that can perform in many different situations. For those shopping, the Weatherby accepts any chokes with the Beretta/Benelli mobile choke thread pattern. (I field quite a few questions regarding this.)
Since stock capacity is never enough, a +2 magazine extension was installed. Similar to the modification I performed on the 12 gauge, I found that the Beneilli Nova thread pattern mated perfectly to the stock Weatherby magazine tube after some filing to remove the crimped end. However, this time I went with a Choate extension kit and could not be happier with the results. Aside from being one of the only companies that make a 20 gauge magazine extension, their product features a much stiffer spring and includes a barrel clamp with sling adapter for about the same price as the TacStar. The spring will need to be trimmed slightly to get the perfect fit, but the extra tweaking was well worth it.
Handling the gun, I could feel the significant difference in weight between the 12 and 20 gauge. Even with a full 8 rounds the shotgun was extremely manageable, making this a perfect package for women or smaller shooters in search of a high capacity 20 gauge semi-automatic home defense firearm. Just what every home needs!
