These guys speak the truth. As much as people fight it, reloading is ideal with antiques. You can find commercial ammunition that is safe in antiques, but it's usually very specific and you must make sure your gun specifically is safe to shoot it, hence why reloading is ideal.
There are also a couple moderators and experienced CGN'ers on the board that you can ask for advice as well. You'll get an idea for who they are by researching past threads.
For my part it's my opinion that you get what you pay for. Buy nice or buy twice is a very strong rule with antiques. They command premiums because of the exact reasons you want one, as well as the fact that damaged or worn antiques are very difficult to fix. I like them because I enjoy tinkering, but it takes a lot of work to actually fix a broken antique to the degree it's working reliably... unfortunately I know that from experience.
IMHO - Best bets are Webleys, Colt SAA, French 1892, French 1811. Some of the German revolvers are supposed to be good solid ones too.
Regardless with what you chose, reloading and black powder are the norm.
Add to that list Reichsrevolvers - probably the simplest of the antiques. All of those guns listed by CMichaud as well as the Reichsrevolver have modern commercial ammunition at more or less safe pressures available. There's some debate on pressures for the .455 and 8mm lebel for the 1892 - both made by Fiocchi. I suspect CMichaud meant the 1873 instead of 1811 but I'll leave that up to him to discuss since I definitely don't know everything on the subject, even if I enjoy talking like I do.
The first recommendation I have is to spend time reading and researching yourself, and don't base any decision on a few casual remarks from anonymous people on a gun forum. Otherwise you will be disappointed, and you will deserve to be. Half assed effort gets half assed results. There are lots of sources of information now days.
The other recommendation i have is that if you are going to get into antique cartridge firearms then it is compulsory to reload. If you don't reload you are wasting your time and effort with antiques.
Good sound advice. Searching the forum will give you tons of info on various guns and their pros and cons. More research on bore diameters, years of manufacture, cartridge chamberings etc will help some more. For your knowledge, some SAA's, Webleys and 1892's are not antique due to age or caliber. You must understand antique law very very thoroughly to understand what you're buying and also how to be a good legal owner and target shooter after buying. Remember, most law enforcement don't know the antique laws, to them you're just a twit in the woods with a handgun - you will need to know how to politely and properly explain what's going on, and for that you'll need to know the laws very well yourself and have paperwork to back yourself up. End of the day if you're friendly, polite and knowledgeable you might be able to bring someone around to our side.
