Well, it's been a while, but here is my report.
In my search for a derringer, I found one made by American Derringer Corp. in Waco, TX. I got it at a good auction price on GunBroker.com from a seller in San Diego, CA. The local FFL dealer I've done business with before has been closed due to covid and general nonavailability of ammo, etc., so I engaged with Frontier Firearms, another local gun shop in Kingston, TN, to do the transfer. They directed me to their website where I provided the particulars about the seller and so on. They emailed their FFL to the seller who promptly shipped the gun to them and sent me a tracking number for it. The Frontier Firearms FFL transfer web site was adamant, stating in at least six prominent spots, "Do not call us. We will contact you when your firearm is ready for pick up." So...eight days after the USPS tracking number indicated my package had been delivered to them, I decided to hell with their directive and called to find out what was going on. Long story short, the gun had been sitting there for 8 days. Frontier claimed to have called and left a message but there is no record of it on my phone. Anyway, I am now in the market for a new gun dealer.
This particular gun appears to be very well made, it has no rough edges and locks up tight. The grips are very wide and have squarish edges on the back. The gun has a super stiff trigger pull and very heavy mainspring. The American Derringer is quite a bit smaller/lighter than the Bond, but a little bigger/heavier than a Davis derringer. Mine is a stainless steel version with three inch barrels.
I took it to the back yard and tried a few shots. With a light .38 Special target load, 3 grains of Bullseye and a 130 grain lead bullet, recoil seemed pretty tame. It shot high, like maybe a foot at six yards. Then it was time to try it with a black powder .38 Special load of 19 grains of FFFg and a 125 grain bullet. That time, recoil did not seem so tame and it was super loud! I am in no itching hurry to try full-power .357 Magnum ammo in it.
I also tried some "hornet" loads. They were made with .357 Magnum cartridges, a Federal primer, 2 grains of Bullseye, a tissue paper wad and the rest of the case filled with crushed walnut shells. They make a pretty good "pop" when they go off, they don't damage a painted surface, nor do they do much damage to wasps or carpenter bees. I don't think I'll bother with anymore of them.
Until I make some more comfortable grips for it and lighten up the trigger pull, I'm reluctant to attempt shooting it over my chronograph.
