For more than 20 years, I have owned one or more NAA revolvers. I have never had the hammer slip off the safety notch. This is over several years of carrying it in the back pocket of a pair of jeans while working in the oilfield blowing stuff up to clear rock for locations.
That being said, the Pug is nice little compromise in a tiny little pocket gun. The sights help keep it paper plate accurate out to 10-15 yards and the rubber grips make it fairly easy to manipulate.
I carry one in my pocket at home or when out and about in a rear pocket as a backup to my Seecamp or larger gun.
I prefer the ballistics and accuracy of the Black Widow, which has a 2" barrel and is silly accurate. I can knock out the X ring of a silhouette target with ease with my little gun. I took off the larger grips it came with and put on a rubber pair like what the pug comes with.
They are great little guns and .22mag is nothing to sneeze at when it comes to penetration, even out of the little NAA guns. I wholeheartedly endorse getting one. You will love it.
