@allyncooper ,Received my Trapper pistol yesterday. Looks like a nice piece. I bought the finished model rather than the kit because it was only $10 more and I am too busy now with fishing and camping as my leisure time activities. I intend to put together a kit Kentucky flintlock as a winter project when I'll have more time.
Instructions were generic so anyone know what spec cap I use and where I can get them? I have a Deerhunter flintlock so percussion sidelocks are new to me. I've heard they are tough to find just like BP.
I don't own one of those pistols, but I am confident that it would use #11 caps, which seem to be the standard size for sporting long arms and single-shot pistols these days. Even if I'm wrong, replacement nipples are easy to find and inexpensive, and you can get one specifically sized for #11 caps.
As for caps, I don't know what to tell you. Caps are difficult to find, and if you do find some to have shipped, you'll pay an extra Hazardous Materials ("HazMat") fee. Check your local Big Box sportsmen's suppliers regularly for caps. They trickle in, and sell out fast. I would be careful shopping online. There are websites out there for "businesses" nobody has heard of before that claim to have stocks of percussion caps and primers for very attractive prices. Beware. Many of these are outright scams, and some want to be paid in "cryptocurrency," like Bitcoin. Be especially wary of these. You'll want to stick with sellers who have an established reputation. If you have any concerns about a dealer, search for comments on the Web, or ask right here on the forum.
Those of us who have been in this for a while have learned that shortages come and go, and when commodities like caps are available it is wise to buy a few extra. Stocking up and being prepared is not the same as hoarding. However, if you are just getting started, you would not have anticipated this. I understand... I've done a lot of shooting with muzzleloaders, as well as breech loaders with factory ammunition. However, I'm just now trying to get started in blackpowder cartridge reloading. I have everything I need except primers, which are evidently being pulled into that same black hole with percussion caps. You can't get primers for love nor money right now.
Anyway, I hope you enjoy your new sidearm. I understand those Trappers can be very accurate and reliable... A good choice for an entry-level pistol.
Best regards,
