What are 9mm Shotgun Adapters?
Shotgun Adapters frequently called Chamber Reducers or Shotgun Barrel Inserts. Our shotgun adapters allow you to use other types of ammunition in a Break Action Shotgun. Including double barrel and over and under double barrels in addition to the popular single barrel break action. We offer several different versions to suit your preference in ammunition, as well as length. 12 and 20 Gauge shotgun adapters are our most popular adapters followed closely by the 410. 16 Gauge is something we plan on expanding in the future.
9mm Shotgun Adapters
Most of our shotgun adapters come in different lengths to suit your needs. Some like the secure storage and portably of Shell length adapters. Whereas some are looking to get the most fps (feet per second) or accuracy out of their adapter. Black Oxide has become our standard finish. We can offer unfinished adapters during our production if you have requested one.
FPS (Feet Per Second)
9mm Shotgun Adapters
As a general rule, the longer the adapter, the more FPS it produces. However, with low-pressure rounds such as the 45 colt, the fps difference is minimal once past the 11″ length. If you are interested, here is an excellent website that gives a good idea of fps per inch BBTI. All of our shotgun adapters are entirely made in the United States and are an affordable addition to your break action shotgun. Thank you for you interest in our Shotgun Adapters or Chamber Reducers.

I bought one of the 2 3/4 9mm-12 gauge adapters and it’s a really really tight fit in my nef single shot 12 gauge it has a 3″chamber so it should fit just fine, I also added a light coat of rim oil to the adapter but no luck it’s still a really tight fit, hopefully the more i shoot with it the more it breaks in and losings up in time….

I can will send you some slightly smaller O’rings to try if that is ok with you

Fits well. Shoots extremely accurate. I need to pry the 9mm luger casings out as they seem to case form to the 9mm auto chamber. A small flathead screwdriver suffices. It is not too hard at all.

By far the best adapters on the market. Even with just the 2 3/4″ I can shoot fist sized groups at 50 yards with open sights
