This is the post that derailed the train. I had penciled this in to come out in mid-July. I moved it to late July and then late August and then I gave up. These were all range trips scheduled that got superseded by something more important. While it is not critical for me to go to the range and certainly not for the purposes of taking pictures and gathering information to write here about it, it has been rather frustrating to plan on doing something and to get overridden by someone else’s poor planning agenda.

I am leaving that all behind now. What are we looking at? It is effectively a 20 gauge shotgun firing 9mm ammunition. This is accomplished by the device in the middle called a barrel adapter. The basic idea is that the adapter fits into the shotgun chamber and that has it’s own chamber for some smaller caliber.

Barrel adapters are not new but they are unique. There are several boutique manufacturers that seem to machining operations at their core. The biggest knock is that they are expensive and made to order. It tends to be $200 per adapter. That is actually double what I paid for the shotgun and so I have held off for a long time. It wasn’t until I discovered this four pack of adapters for a little over $200 that I made the decision to buy.

I have one break action shotgun. It happens to be a single barrel but these things do work in doubles. In theory, you could have one barrel loaded with shot and one barrel loaded with a pistol caliber. Assuming the premise of all of this is good, that is a pretty compelling amount of versatility for situations like small game hunting.

The devil is in the details here. Barrel adapters come in different lengths and you can even get them rifled and unrifled. It would be much better to have a rifled adapter from an accuracy and repeatability standpoint. Mine are 8″ long and rifled. I think it is ideal for the situation, not too long but yet some of the benefits of a longer barrel, kind of like shooting a long pistol. Considering that the chamber is included in the overall length, it effectively makes it a 7-7 1/2″ barrel.

The big thing to consider is that barrel adapters are an ad-hoc situation. I found it helpful to have a prying tool to remove the spent casing. The shotgun shell ejector/extractor will not reach the smaller diameter pistol casing. I imagine that a finger nail would work but you also risk putting you fingers into sharp, hot metal.

Just for benchmark purposes, I shot 115gr 9mm at about a 10 yard target. I found it to shoot about 6″ higher than the aiming point. There are of course many variables that could change all of that. Would a different brand perform differently? What about 124gr or 147gr bullets instead of 115gr? Given that kind of discrepancy, it seems like a 50 yard shot might be closer to dead on. That is good news from a hunting standpoint but this is a shotgun and lacks rifle sights which would make a big difference in accuracy as well.

This kit came with adapters for 9mm, 357 magnum, 45acp and 45 colt. Most shooters know that 45 colt is the same diameter as the 410 bore shotgun, so in this case the chamber is actually 3″ to accommodate for the shot shell. Believe it or not, I do not own a 9mm pistol and so the rest of the calibers I will be interested in comparing velocity data between effectively a 7″ pistol (the adapter) and a regular handgun. That is future work to do.

The first thing a new firearm gets from me is a function test. Does it actually work? I know that this is not a firearm but essentially it is. In fact it is a non-branded use and so function testing is definitely more important. I am happy to report that everything worked like it was supposed to. I am now going to go on the process of testing all the calibers an permutations for future range trips.

This shotgun is part of a set that is no longer made. I originally purchased it to haul around in a survival kit. It is a youth model and I was originally going to start my kids on it but I had several very unpleasant recoil experiences that I would not let them use it as it was too light. That being said, I kind of wish that I did not own it. It was so inexpensive that it really is effectively worthless. Hence the desire to seek more utility from the setup.

End Your Programming Routine: Let me bottom line it. I would not go out and purchase a break-open shotgun to then buy adapters for versatility. I still have a lot of testing to do but I don’t see the accuracy with the sights and the difficulty to reload as better than a 9mm handgun. It will also never replace my 870 as a shotgun. But, since I already own it I might as well have some fun and try something different.
