I looked at the 332 at one time, it disappeared from production before I got back to the shop or so it seemed. They had as short of a lifespan as the 300 and Ideal which came before and were other Remington flops. Maybe if Remington would have touted its own merits rather than compare it to a gun discontinued more than half a century earlier the 332 would have made it to its 5th birthday.
The 332 was a standard production gun with some fitting and assembly done in the custom shop, not an actual custom shop offering. I believe barrel assembly/regulation was done there as was fitting the side plates. There may have been other areas the custom shop worked on but those are what I seem to recall.
The lack of production makes for few reviews on the gun. What I recall most from my notes is the gun opening on firing? This seemed to be less prevalent with the 332 than previous models but it still occurred. Whether poor fitting, low quality metal, or poor design caused this to happen I don't know but it can be a relatively expensive repair on a common model and potentially even more on something lesser known as parts may not be readily available and the base knowledge of how to do the repair is unknown.
I've seen these on the used rack on occasion but have passed on them every time. The brief lifespan and lack of parts and support are deal killers for me. I would consider one if priced in the "disposable" range in the event of parts breakage or wear but that hasn't happened yet. I am very leery to put much money out on brands/models that have such unknown histories. One occasionally finds a gem but more often there is a reason these models came and went so quickly and quietly.
