My FN FiveSeveN was a bit of an impulse buy, I had shot lots of pistols in a lot of pistol calibers but this was one unlike any I had shot before. I do absolutely love the pistol, its grip is a bit big so it isn't idea for my wife to shoot but it fits in my hands just fine.
I don't recall exactly where I found these guys but I came across MasterPiece Arms
and did some browsing on their site. Looks mostly like MAC10esc firearms in 9mm and 45ACP, I then came across this
, one chambered for 5.7x28mm. I have often toyed with the idea of an P90 or 5.7 upper for an AR but have always and most likely will have other priorities. It is however a cool little pistol as are some of there 9mm/45ACP versions so if it is something any of you had ever wanted you might give them a look. Much to my surprise their prices were what I would call pretty reasonable.
