Minor differences
"As far as I can tell, after close examination, they (P.38 and P1) are the same, except for the Aluminum frame on the P1..." You had me checking again (I hate making affirmations when I'm not 100% sure):
Yes, internally, there are minor design changes (refer to illustration from NRA
Guide to Firearms Assembly) on my 7/57 (July 1957) P1 :
J) Firing pin is different: now cylindrical where there was a flat in middle,
G) Firing pin retainer pin is smaller in diameter,
H) Cartridge indicator is shaped differently,
B) Firing pin spring is shaped differently: rear square hook portion now faces forward to ride on the widened flat in piece H which is closer to barrel.
I see these changes as perhaps simplifications in manufacturing. I don't beleive they affect my previous appreciation in any way as far as reliability and safety are concerned. The Walther P1 pistol was use by the Berlin Police until the late 1980s when it was replaced by the SIG P226, another of my favorites.
By the way you can get them cheaper now: "(PSAR698)- Walther P-38 Pistol, Cal. 9 mm Parabellum, Post-War Alloy Frame, the standard sidearm of the German Police. Comes with spare mag/black leather holster, restricted, Condition: Excellent, $ 395.00 Can" at: http://psmilitaria.50megs.com/pistol.html
Believe me, you won't find a finer 9mm pistol for that price, period. As a footnote, in the 1970 series "The man from U.N.C.L.E" their (then) super hi-teck pistol was a variation on the P.38 theme. Maybe that's where I got the crunch on the P.38.
