Sticky: Cracked P-1 slide

Hi all...new to the forum. Looks like I will learn alot here.
I have a 1960 P-1 that much to my dismay now has a 1/4" crack on the slide.
My question is I have seen some "new" P-1 stripped slides
on Ebay today with no serial no. for a good price. Would
there be a problem with these fitting my 1960 P-1? Any fitting
issues? Thanks for any help.

Since found out that the slide on ebay is an 82 manufacture.
But why no serial no.?

Cracking slides are common on 1960's non reinforced slide P38/P1's. I've seen more cracked slides on Manurhin P1's but this could be because I've seen more Manurhins.
.
Bundeswehr and certain police slides are numbered to match the gun. If the slide isn't serial numbered it may be a new depot replacement slide. Installation should be performed by a gunsmith.

Ok, thanks. I was just wondering if the good price on the slide
would be offset by any major modifications made by the gunsmith.
I have really enjoyed shooting it...it was all matching and fairly
accurate for a 54 year old shooter.

Why would you want to pay $40 on eBay when brand-new ones are available from CDNN for half that?

I find myself asking what is meant by the use of the word "common", Milspec. I have an early 1960's non-pinned frame, "thin" slide P.38 that's probably got six thousand rounds downrange and sure isn't showing any signs of letting loose anytime soon. But then, I don't abuse the thing by feeding +P+ (or whatever) overloaded ammunition through it, either. This could be a factor, I'm sure, but I still wonder what is meant by "common".

The cracking of the slide at the locking lug cutouts described by the OP is an issue common to the various "thin slide" versions of the P38/P1. A reinforced slide was introduced that was less susceptible to stretching and metal fatigue which largely resolved the issue.
.
My '66 BMI surplus P1 shows signs of extensive firing though it is in overall good condition. Since I don't know the amount of wear the slide has been subjected to I do not fire this weapon. My virtually identical '64 police (Hesse?) P1 is in a similar condition so I don't fire it either. My '68 P1 commercial has the same slide as the other two but appears newer. Still, I fire my reinforced slide '72 P1 instead...if only for a perceived margin of safety.

What is not commonly understood by many P38 shooters is that the gun was designed in the 1930s to use the ammunition of that day, and that the addition of seemingly small increments of power has disproportionate consequences. The increased momentum from a few additional feet per second of slide velocity is not in direct ratio but is squared.

Prewar and WWII-era 9mm was not loaded particularly hot, and the ammunition was held to tight tolerances by the German military, so the slide-cracking problem likely did not show up then. Not until the '60s, after extensive use with heavier police (and perhaps military) loadings, was it apparent that the designed calculations for slide mass, materials, heat treatment, recoil springs, etc. were inadequate to absorb the added momentum. Slides were stretching and cracking, and the same is true for wartime guns imported decades ago as surplus and now indiscriminately used with whatever happens to be on sale at Walmart.

Mike: any recommendation for ammo to use in wartime P38s? I tried WWB and wasn't all that happy with it. How hot, velocity-wise, were the WW2 loads?

Here is some 9mm data from Gustav Genshow & Co. 1939

Muzzle meters per second 327 (1,072 fps)

at 50 meters 303 ms (994 fps)

at 100 meters 284 ms (931 fps)
