Impossible to answer without the maker's name. Even then....
I have the same firearm I belive, I have fired Remington .22 short rounds. Mine has a slight problem with having to strike twice to set the round off He Actually Hates It! I also have one and it also has to strike twice to fire. Or it did. A gunsmith "improved" it to where it now requires 4 strikes to fire. You can get some parts as it is a copy of a Colt. Google "butler derringer parts".
I have seen them recently at auction in the $175 dollar range.
It is called a pistol
A short recoil, semi-automatic, single-action / double-action pistol, the M9 uses a 15-round staggered magazine with a reversible magazine release button that can be positioned for either right or left-handed shooters.
You need a gunsmith
