I got one in a trade a few years back and now have three of them, all 22 mag's. As was mentioned, they are very well made, and once you figure them out, good shooters with good ammo.
Accuracy with them is good, but learning how to aim them may take a little getting used to. If you have one with the Big Dot sights, aiming is pretty straightforward. If its just got a front blade, trying to figure out what to use for vertical alignment is more difficult. Best way Ive found to aim with them is, use the front blade for the horizontal alignment, and sight down the top of the receiver fo the vertical.
Grips will likely be a personal thing. All three of mine were used and all came with different grips, the PUG had a Houge rubber grip, one had a set of smooth wood on it and had a couple of others, plastic/bone grips with it.T he last had one of the large, folding grips on it.
My favorite is the Houge rubber grip. Its a little fatter than the others and much easier to hang onto. It may not be as pretty as the others, but it gives a more solid, "one finger" grip that works best. Makes getting ahold of the gun a lot easier too. The others are too thin and slippery for me.
I understand the idea behind the folding gip, but I didn't like it. Made the gun bulky, defeating the purpose of the smaller gun, and its fiddly. And anyone whos seen one knows what that thing is in your pocket.
This is one of mine with the Houge grip on it. The target was shot at around 5 yards, and as fast as I could thumb them off.
I got a couple of boxes of ammo with each gun when I got them and burned it up playing with the guns. It was a mix of a bunch of different stuff, including a box of Remington, which was the only one that had issues. Best as I can tell, their bullets are undersized and youll get keyholing.....
The ammo I settled on is the Gold Dot SB "short barrel". Accurate and no issues.
Youre going to have to decide if you think something like this is really viable for something you want to trust your life too. For me, they are still considered a toy and kind of a joke, but they easily be a deadly joke. Ive been carrying one in my back pocket for a couple of years now basically just as that, a "Noisy Cricket" joke amongst friends. At best, it would be a third or fourth line gun if I were to categorize it.
