I haven't seen a PL sell for under $4,000 for about 2-3 years.
You can still find a nice non-PL, 95%+, E/N, PPK for under $1,000.
If it has a PL grip on it, then it's near $5,000.
Seems that would make the PL grips alone worth approx. $3,500 - 4,000.
Taudelt, not clear if the seller is indicating that he traded for it during WW2, and thus the PL is his bringback. If his bring back, then # he put in holster should NOT be his social security number (SS#), but should be his military ID#, which is different from his SS#. If his bringback, with last digits of his SS#, then I would be suspicious of his story. You can alway take good detailed external & internal photos of the grips and post them, and then we could compare them.
Lloyd, Ditto on the fake grips. Spoke w/ Joe W. some while ago, and he told me that he has seen fake PL grips with the spring steel inserts. Apparently, there are fakes out there which are better than the fakes pictured on my website. Unless I were certain about the authenticity of the grips, I would not buy one without an inspection period where I could return the pistol, and I would use this period to send photos, etc, to other collectors to help me authenticate the grips. Aside from some scattering within a serial number range, the only unique characteristic of a PL is in the bakelite grips, and since the grips alone are worth at least three times the value of the pistol, it is essentially important that the grips be authenticated.
