the ruger is a nice firearm. i bought mine for $310. same one sells anywhere from $280-410. great gun. will eat any ammo you buy. it's a heavier gun, but i carry mine with a UTG shoulder holster during the cold times.
if that offer was on the table for me, i'd have me another anytime.
the decocker is a great option, just make sure when you use it, you still point it in a safe direction.
all in all, if it's your first gun, definitely a good choice
