Well thats the thing I live in massachusetts and here we are not alowed to have revolvers that dont have the transfer bar safety.
Howdy
I live in Massachusetts too. That statement is incorrect. Whoever told you that does not understand the law.
First off, forget about converting the C&B Uberti to cartridges. As has been stated, they are specifically designed to make the conversion next to impossible. Whoever told you they can be converted does not know what they are talking about.
OK, let's get back to Mass law.
The Attorney General's 1998 handgun regulations, among other things, state that any NEW handgun sold in Mass must pass a drop test. No where does it state anything about a transfer bar. The regulations say nothing about what you are allowed to own either, it talks about what you are allowed to buy. A fine distinction.
Here is a link that will take you to the AG's 1998 handgun laws.

Yes, a standard Single Action revolver with a Colt style mechanism will miserably fail a drop test. Drop it on the hammer and the sear or 'safety cock' notch will shear and if it has a live round under the hammer, the gun will most likely fire. Now having a transfer bar does not automatically make it legal for sale in Mass. The gun still has to be submitted to the state for destructive testing. Which is why NOBODY other than Ruger has gone the distance to help out beleaguered Mass gun owners. Ruger has spent a lot of money submitting their revolvers for testing, and most of them are legal for sale in Mass. Ruger has not spent the money on a few models, but you can walk into any gun store in Mass and legally buy a Blackhawk, Vaquero, or Single Six, as long as you have your LTC.
So if you really want a Single Action revolver option one is to simply buy a Ruger. Forget about the Colt Cowboy, they are not manufactured any more, and were never submitted for testing.
OK, Option Two: There is a grandfather clause in the law. Any handgun that was 'legally registered' in the state before October something or other, 1998, is exempt. I can't remember the exact date, but you can look it up if you really want. So if you find an Uberti or Colt, or any other revolver that was in the state prior to that date, you can buy it. This is why you start haunting the guns shops and gun shows. These guns are getting rare, but they are out there. Trust me on this.
Option Three: buy a 'regular' Cap & Ball revolver and buy a conversion cylinder for it. This may be what you are referring to when you are talking about conversions that have been done. If you buy a C&B revolver, it is treated by US law and by Mass law as an antique and no paperwork need be done. You can then purchase a conversion cylinder for it that you pop in yourself. Pop the cylinder in and it is a cartridge revolver. Pop the cylinder out and put the C&B cylinder back in and it is an antique. Presto! If you are going to go this route, I heartily endorse the cylinders sold by Taylors and a few other places, particularly the ones designed for the 1858 Remington. I have a couple myself. The downside of this is that you spend the money to buy the gun, then more money buying the cylinder. But it is legal in Mass. If you are nervous about it, keep the percussion cylinder in the gun until you get to the range, put in the cartridge cylinder and shoot, then pop the c&b cylinder back in for the ride home. Frankly, I have never bothered. I will caution you, there are some other brands of conversion cylinders that require modification to the frame so the gun is fully functional. If you modify the frame, you have permanently changed the gun over to a cartridge gun. Yes, you can own it, but it is yours forever and you can never sell it. That's why I recommend the Taylor's cylinders, no modification of the gun is required. These cylinders are proofed for mild Smokeless loads, specifically for Cowboy Loads.
Here is a link to the Taylor's conversion cylinders.

Option Four: Get a C&R license. A Federal Curio and Relic license allows you to buy firearms, including handguns that are on the C&R list. Basically, any firearm that is at least 50 years old is a Curio and Relic, with some exceptions. With a C&R you can walk into any dealer, in any state, and purchase a C&R firearm over the counter and walk out the door with it. No nics check, no federal paperwork. You present a signed copy of your C&R to the dealer, he gives you a copy of his FFL. There are book keeping requirements with a C&R. You must keep a bound book. The ATF can audit you. You MUST NOT use your C&R for commercial purposes, it is for collection ONLY. As far as Mass is concerned, once you cross the state line with your C&R firearm, you have 7 days to fill out an FA-10 form and file it with the state. All completely legal.

OK, I admit it is tough to be a Mass gun owner, but you do have options.
Sorry about the Uberti 1873 C&B, you really cannot convert it. That's why they are sold in Europe, where gun ownership is even more restrictive than here in Mass.
