I own both a Forty-Nine (in .40S&W) and an FNP-9 (in 9mm-duh)
The Forty-Nine was my first full power handgun. The ergonimcs were what swayed me to it and after the AWB died, the availability of full capacity magazines further sweetened the deal. The trigger is about 10lbs, but is fairly smooth and the pull is even. Easy to be accurate with IF you take your time. The gun is a finely finished piece although I'm none too hot on the plastic guide rod with captive spring. It hasn't been a problem in a few thousand rounds though. I have never had the gun fail on me. An ammo problem was the only malfunction this weapon has ever had and thats just because the primer didn't light. Recoil is sharp with the .40 but not uncontrollable. It has eaten everything I have fed it from reloads to Wolf to WWB and Speer Gold Dots. As long as it says .40S&W on it, this gun fires it, ejects it and grabs another one. Another thing is that the gun uses a modular design. The slide rails are replaceable by an FN armorer. When they start to wear and the gun feels loose, you can send it in and have the rails replaced. When that happens on a Sig that costs 2x as much, its time to throw it away.
The other weapon, the FNP-9 was actually purchased for my girlfriend. I get to spend the most time with it however. The thing I love about this weapon is that it is lighter and slightly smaller than a SIG P229, more ergonomic than a Glock 19 and sports a higher capacity than both in 9mm. 16 rounds of full power 9mm is a comforting thing at night. The standard rail, an improvement over the Forty-Nine, allows easy attachment of standard pieces. The weapon will fit most holsters for the HK USP Compact and weighs less. It is also slimmer than the HK. Recoil is soft with standard 9mm. The weapon is as accurate as I am. The weapon also has changeable backstraps. One is curved and the other flat. Easily adjustable from shooter to shooter. It actually sounds like the ultimate sidearm for police departments. Low purchase price, soft recoil, same swappable slide rails the Forty-Nine has, adjustable backstraps for officers, high capacity in 9mm or .40 (16 and 14 rounds respectively) If you want, you can also look at the Browning Pro-9 or Pro-40. These offer a magazine disconnect (I think) as well as a manual safety along with the decocker. (the FNP only has the decocker)
Cocked and locked with the ability to decock! Sounds like a winner to me!
I absolutley love mine. I have considered trading/selling the Forty-Nine though...for the FNP-40
As soon as I can find one, I may be bidding the Forty-Nine a teary farewell. The nice thing is that the magazines are interchangable.
I give both weapons a rousing two thumbs up and would recommend them to everyone who asks.
BTW, the FN-49 is a rifle. You'll notice I type out Forty-Nine to avoid confusion.
