I would not give up my 329PD. It is just about the best backup sidearm and all-around woods gun I've found for my needs, especially now with a set of Meprolight sights. Mine has not been shot "extensively", but it has seen on the order of 1000+ various factory 44 Spl. and shot loads, and about 300 rds. of Remington and Winchester 240 gr. standard mag loads (I don't handload as of yet). I don't like the internal lock either, but in all fairness, I've never had it lock up on recoil with standard loads. IMHO, it's pretty enjoyable to shoot with light fodder, and accurate enough for all defensive business. I bought this not as a routine range piece but for a very specific purpose, which is as a last-ditch defensive gun when out in the woods, and treat it as such. Which is to say, I carry it often and shoot it enough to maintain proficiency.
