Solid.
Well built little gun.
Use 22mag ammo. It shoots much more accurately than .22lr. Speer makes a Gold Dot Short Barrel 22mag round for these(GDHP-SB)
The larger wood or plastic finger groove grip is worth it.
NEVER dry fire it. Use fired cases as snap caps. You'll need to turn cases after a snap to align unsmashed rim under hammer nose.
The sideplate screw can work loose. Check it periodically(note: it has REVERSE threads). If it works loose far enough it will cause the internal action parts to get out of whack.
Do not buy the version with the skeleton hammer. I believe it is called a WASP. Get a solid hammer version.
Note: dis-assembling voids warranty.
If you do take it down be aware there are several itty-bitty and I mean microscopic small parts in it. Do NOT lose them.
NAA will NOT sell you replacements. You have to send in the gun for repair. $$$$$ and a p.i.t.a.
Please do not ask how I know.
I use one of those El-Cheapo Uncle Mike's neoprene holsters. I cut the plastic belt hook off. Makes a decent pocket holster for very little $.
I use a small Altoid breath mint tin for a spare ammo carrier. It will hold 10 extra rounds wrapped in a small piece of cloth to prevent rattling. Very covert. Fits in any pocket and innocuous.
