Yes, it's an ac44. It's in the i block. coincedentally over on the P.38 forum, a member picked one up about 2k off this one. It's frame is plum too, but not to the extent this one is. Could have been a batch of high nickel content steel or just not having the bath mixed correctly or the temp set right. The hammer on my 18 year old sig turned plum after a couple years, as did the extractor on my HK Tactical.
I shot one mag through it, and it shoots fine, but the spring for the take down plunger is weak and should be replaced if anyone was going to do some serious range time with it. I'm not, I just needed something to fill my bugs bunny holster...
I just don't care to have guns around the house that are of collector value that I would be doing significant damage to the value of by shooting. I like mine about 85-90% that I can pop off a few rounds in every now and then.
