I have the 34". Quality is fine, especially for the price, but know there are no single shoulder-strap attachment points and no side carry handle... to it's pretty much backpack or nothing. It's not a problem if it's the only bag you're carrying, but it becomes a problem if you're trying to lug multiples.

Kel-Tec PR57 5.7x28mm 4.64" Pistol Black 20rd - $249.99

It's under 14oz and very thin. Makes for a nice compact, simple carry gun with a 21rnd capacity. I have one and like it for what it is.

Kel-Tec PR57 5.7x28mm 4.64" Pistol Black 20rd - $249.99

I don't think there is any mechanical or tactical advantage to top load, but I don't think that is the point of this design. Considering the many restrictive states, counties, cities regarding magazines and appearances, I believe this design is an option to allow higher than 10 round counts for those buyers. As a defensive package in such a restricted location, I can understand carrying this as primary backed up with a 38 snub. Just my guess on this Kel-Tec product. My advice though would be to buy a bus ticket and move elsewhere. As an FFL holder I am absolutely disgusted by the obscene and endless laws I and my customers have to navigate. "Infringe" is an understatement.

Otter Creek Polonium 30 - $439.99 (Add to Cart for Best Price)

I did indeed do that and it wasn’t working. Also the $532 was a reduction from a higher price $589 IIRC when added to cart. Looks like this was fixed. Thanks for being a master of the obvious.

INLAND Suppressor 22LR BLK Aluminum - $225.99

There needs to be more companies to embrace the maglite styling on cans. The fancy designs add machine time and cost. Give us knurled black tubes.
