If I might suggest then go for an M1841 Mississippi and a Colt Navy pistol. You're looking at about $500 (new) for the Mississippi. THey are only made by EuroArms now but several years back an outfit by the name of Zoli made them as well and you can sometimes find them for the $300 range on the used market. There were a LOT of different versions of the Mississippi so as you get more money you can upgrade by adding a different rear site, different front barrel band front site bayonet stud etc. Don't buy a Zouve and call it a Mississippi... they don't look the same and it is a glaring mistake, a lot of events forbid Zouves alltogether because they were never issued during the war and absolutely never saw
CS Service. Send me a PM w/ your email if you would like some pics of an M1841. My own is a "Colt Standard", which means it has a Colt rear site and a band w/ stud for the bayonet... and is one of the the types carried by the 4th MN VI, my primary impression.
As for a Colt Navy... Places like Gander Mtn, Sports Authority and many other sporting goods stores sell a kit w/ a Colt Navy for around $150 that includes flask, lube and various Black Powder gear you will need for a pistol. Though I might suggest Cabelas as they seem to have the best price.
I don't know about advising you to pick up shotgun or not. I know some events refuse to allow shotguns on the field under any circumstances.
One thing I've read about in several places from period accounts has been
Cav units who were dismounted trading in the
Cav equipage and arms for Infantry gear when they lost their horses. I don't know if this ever happened w/ the 11th. I thought they managed to stay mounted through most of the War.
You've chosen a hobby that will likely catch you up in it and I suspect down the road when you have the opportunity to pick up an original arm of the kind carried by the 11th you likely will move heaven and earth to do so.
Now, please don't take the following in the wrong way. I'm not trying to be condescending, mean or rude I'm trying to pass on knowledge that might help you out as you get started. I have learned to be extremely leary of the plethera of "dismounted"
Cav units I've run across; both Union &
CS. My experiances w/ dismounted
Cav have almost all been poor... it was a dismounted unit that sent wonder wad my way at an event and up here in the Upper Midwest there are several Dismounted
Cav units that are generally banned from events because of a lack of standards. I've seen dismounted
Cav troopers w/ absolutely no knowledge of horses... which is something that really stands out. When I first began in the hobby it was
CS units that impressed the hell out of me w/ their attitudes safety and their complete authenticity package. Note that I still remember that Texan Cowboy... 15 odd years later. A glaring warning sign might be something like a preponderance of Zouves or Hawkens Rifles in a unit; while they are an inexpensive option they are not correct in any sense and they stand out as incorrect. I've seen a man go out on the field w/ a Hawken and no less than four pistols...
Those boys of the 11th were some of the toughest
Cav the
CS had to offer, they were Texans through and through and by late 1863 they were Veterans of some of the toughest fighting of the War. Many had fought Commanches before the War, some were veterans of the Mexican War and all were a very tough lot. They were generally used to a bit of hardship and many were used to life in the saddle. They deserve every bit of honor and respect you can give their memory. There are several excellent places to look for solid research on texan
Cav. I might suggest
www.authentic-campaigner join and lurk for quite a while. Take advantage of the excellent search function and ask serious questions only after exhausting the search function. It isn't always what I would call a friendly or tolerant place but the information held w/in is nothing short of spectacular.
www.37thtexas.org/html/chboys.html is another unit w/ an excellent reputation. There is also a
Cav web ring out there w/ many excellent sources.
Again, good luck.
