NAA Pug .22 LR - .22 WMR 1in Stainless Steel 5rd - $347.67 (Free S/H on Firearms)

Well your link is for .22lr, the pug listed above is .22 mag. I bought this in December 2015 for $185: http://www.budsgunshop.com/catalog/product_info.php/products_id/51202/NAA+NAA-22MS+Mini-Revolver+5RD+22MAG+1.125%22...
For some reason it's $40 bucks more at the time of this posting. The standard NAA .22mag is a closer comparison than the link to the gun you provided. But why the hell are NAA mini revolvers jumping 30% in price over the past two months?

I have the 1 inch .22 mag that I scooped up for $185. It's less noticeable in your pocket than a cell phone. I understand your point, but it has its place when you want VERY concealed carry. I keep it in my garter when playing poker on a steamboat.
It's also fun to shoot (but a pain to reload, the sidewinder may alleviate that) and fairly attractive. If I buy another, I would consider the "sheriff" or the "black widow" or a 2 inch "sidewinder". I would choose any of those three over this "pug". Apparently the two inch barrel provides enough velocity to get hollow points to open up. The one inch barrel doesn't provide the fps for good expansion. Then again, I wouldn't want to be hit with a .22 mag no matter how much the bullet expanded.

the non tritium version of this is about $100 off this price, if not $125. i dont see why one would need to spend $100+ on tritium in this case, unless $100 is burning a hole in your pocket.. then by all means. but fwiw, i dont think you can add tritium later, or at least i have not found anyone who has nor the tritium to do it. in fact i have not even managed to find the size and specs for tritium replacements (and i have tried quite a bit)

believe it or not, the version of this gun with the push button pin (non pug) is easier to manipulate than the pug's swivel pin.. its cheaper too. the pugs plastic sights are an upgrade over that other versions 'cowboy sight' (basically a metal blade up front with a minimal/nonexistent notch in the rear) though...
check out the grip options when buying one of these naa's as well, because you can save some $$ factoring that in too. the pug grip is routinely $20, the flip grip holster is $38, and wood grips are more if i remember right... by the time you pay for extras you might as well buy a second gun for the $179 or whatever they want for the non-pug version

The "safety"? Do you mean the notch that keeps the hammer from resting on the primer? Or do you mean being on "half cock"?If you're looking for a safety on a revolver, you're going to be looking for a long time.
