38 Special Shotgun Adapters for 410 Shotguns

38 Shotgun Adapters Allow a 410 Break Action Shotgun with a 3″ Chamber to use 38 Special Ammo.

Single as well as Double Barrel

Heavy Duty Steel Construction

38 Shotgun Adapters Rifle dimensions are .355″/.349″ with 6 lands and .125″ wide with a 1:12 twist rate.

Black Oxide coating as a result provides notably better corrosion protection (for maximum corrosion protection keep a thin coat of oil on the insert)

(Because of the thin wall required for this insert Therefore  I recommend using only standard Load for 38 special ammo.  In addition If reloads are used make sure the pressure stays at or below the standard PSI range)


Please be aware that the 18″ 410 adapters may not work in all shotguns, depending on the bore diameter.  Shotguns with tapered bores may not fit.  Due to the already thin wall it is not possible to make these adapters any smaller.

What is a tapered bore?
A tapered bore is exactly what the title implies. The diameter of the bore gradually tapers down from breech to muzzle. The amount of the taper is slight — perhaps one-thousandth to as much as two-thousandths of an inch; but at the time this service was performed, the measuring tools needed to accurately measure it weren’t commonly available. So, most of the makers didn’t actually know how much they were tapering their bores — just the fact that they were.

What are 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.

FPS (Feet Per Second)

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. If you are interested, here is an excellent website that gives a good idea of fps per inch BBTI. Our shotgun adapters are an affordable addition to your break action shotgun.

    What’s not to love? Affordable, excellent quality, and accurate too! This adapter let me get my old 410 out of the cabinet for the first time in several years and shoot it inexpensively. My 7 year old daughter probably would’ve shot up all my ammo if the gun were smaller and easier for her to hold, she loved it as much as me! Another excellent product and I will certainly be adding to the couple I have!
