If you're going to a free state you can buy one like new cheap and have 20 round mags, so yes, you should get one. Got mine Tuesday and bought a small supply of FNss197 and and Federal 40 gr FMJ. The ammo was $30 and $35 before tax. The gun looks like the offspring of a Cz52 and a Glock 17 and very high quality plastic. The plastic is sort of like a lightweight alloy and feels good, tho not a big fan of plastic guns. The controls all work well. The trigger is better than average for this kind of gun. The FN ammo was accurate, Federal not. I could shoot a 3" group with the FN stuff from sand bags at 25 yards. It could have been better. I load and shoot lots of 45 auto and do not adjust to the snappy recoil of a 9mm and this is the same for me. Somebody really good with a Glock 17 or similar pistol could get better results. The recoil has snap and flash, but it's easy to manage even if a little harsh. I like the cartridge a lot but have no idea how "lethal" it is. I am not military and I have never been a gun carrying LEO, so I have nothing to say about that. To me 5.7x28mm is a new take on 1890's rounds like .30 Borchardt, .30 Luger (big fan of this one) and .30 Mauser/763 Tokarev, all designed for high velocity pistol carbines. The ammo is light and carrying a box of several hundred rounds feels like nothing. I also have no idea whether it's a good self defense weapon - I guess it could be, especially with free state mags. Note that the FN handbook recommends against carrying this single action pistol with a loaded chamber, but maybe that's just lawyer insurance. As for being a controversial gun, why? With no AP legally available, then this is just another low to medium power round. This gun would be great to take into the woods on fishing trips - lightweight gun and ammo, easy corrosion protection, accurate, etc. I think you could get one of these in florida for about $900.00, so I say go for it! As for hand loading, I may try but am not looking forward to it, given the high pressures and close tolerances for charge weight, the plastic coating on the cases and the unavailability of a shell holder for my case trimmer. If anyone has experience reloading 5.7x28, please PM me or post.
PS As for the nightstand, why use a handgun when you can have a rifle?
