I had a look at that 52-2 last night . Its operational but hasn't been very well cared for. Not the factory grips and I don't think its been cleaned since it left the factory. Which is to say its filthy ! Still an accurate gun. I loaded 75 rounds of flush mount, HBWC and it cycled like a champ. Its cheap . Below a grand . Have another one to look at this wednesday that is going for a more average price but has been very well looked after. $350. bucks more but clean and original . Decisions , decisions , decisions .
