I have a model 327 PC, the scandium framed / titanium cylinder 2" snub nose 8 shot. I noticed it has a tritium front sight, but also has two tiny little tritium sights in the rear (it is a fixed sight gun, and the tritium tubes are embedded in the frame / rear sight).
Is this common? I've never seen another 327PC with night sights like this...
Any chance you posting a pic? I had one at one time and IIRC it had a red ramp front sight and no back sight, it was just the channel in the frame like most newer j frames have.
It is definitely a custom job. I have never seen the rear sight done like that by anyone. Good idea. Probably a pretty expensive job. Easy $300 to $400 custom job.
I'm guessing you bought this gun used? Can you contact the original owner and find out more about who did the sight work? I would love to know and I am sure many others here would like to know as well.
