Mauser Hsc is now a jam-omatic with "new" (WW2?) barrel.

[Ignition Override]

The barrel which came with the original WW2 slide fed perfectly, but apparently the feed ramp had been machined. All the ejected brass had bulges
(I never checked brass until after thirty rds.). Not good.
A seasoned WW2 German handgun guy said the brass was "unsupported" by the shape of the feed ramp.

The new barrel supports the brass-no bulges at all. This other feed ramp has a smoother contour than the problem ramp.
When the new barrel is used in the previous slide or the slide which came with the replacement barrel, the slide jams as soon as the magazine is inserted. It should slam fully fwd. Both slides have equally tight springs.

Each ammo round is pushed only part way fwd. in the feed lips, then (of course) it stops the slide from closing. Happens very often. The rounds are Not stovepiped in the normal sense, they are mostly even with the top of the magazine. The ramp is shiny and fairly clean. The magazine is always fully seated. Any ideas?

What kind of ammo are you trying to get it to feed?

Probably the reason the first barrel was screwed up is because someone throated it to feed JHP ammo.

In WWII, JHP pistol ammo had not been invented yet.
So semi-autos of that period were designed to feed only FMJ-RN ammo.

If you want it to feed JHP the chamber will need to be throated to feed it.
But by someone who knows how to do it and not Bubba it like the first one.

From what I remembered, the Mauser HSC in 9 mm Kurz (380 ACP) was notorious for jamming. I knew one gunsmith who refused to work on it. The 7.65 mm (32 ACP) was more reliable.

rcmodel: the "WW2 German handgun guy" at the range also suspected that my original barrel's feed ramp might have been a victim due to hollow point ammo issues.
My .32 Auto/7,65 ammo is all recent fmj, such as Sellier & Bellot. There is a WW2 handgun gun smith specialist (supposedly) somewhere over in West Memphis who can evaluate. Maybe there is a cure.

4v50Gary: Yes, some post WW2 Hsc types, most of which are in .380 Auto, can be known much more for jamming. This seems primarily to be the case among many examples manufactured in Italy ("Renato Gamba").

Part of the HSC feed ramp is on the frame assembly, which is supposed to line up with the barrel feed ramp. It was pretty steep on the WWII guns that only used round nose fmj ammo. If billy-bob got in there with a Dremil tool, who knows what he ground upon....

 

[Ignition Override]

Float Pilot: Even though I'm not familiar with what a specific feed ramp should normally look like, this section on the frame feels and appears very smooth.

If a round often strips only part way out of the mag's feed lips and you have two recoil springs available, do guys ever have better luck after removing a tiny coil from a spring (later maybe two-three)?
Would it improve the timing of the slide's forward movement versus the follower's timing?

There is supposed to be a gun smith specialist in the area for WW2 German handguns.

Have you checked with "Warbird", the moderator on the Mausergun forum? He is my guru on the HSc. I had one that had feeding issues and he guided me to the Wolf Springs for the action and the magazines and solved my problem. And he guided my gunsmith (who was unfamiliar with the HSc) on doing some work on the internals as well. Link below. I have 3 of them now and all function perfectly with FMJ .380. Good luck with yours.

9fingers: Thanks. Will check on the guy you recommend.
With $500 recently spent to acquire this gun and $240 for the extra barrel (+ slide), I'm not sure it's worth much more money for an extra hobby gun.

My WW2 Sauer 38H is superb (also .32 Auto), and only needed the decocker to be adjusted.

A member of the private club told me that 'nearby' in West Memphis there is a gun smith who specializes in WW2 German handguns.

I owned a Nazi WWII Mauser HSc .32ACP several years ago. Don't remember why I got rid of it. Nice gun.

Several years later, I bought a "modern" Mauser Hsc Super in .380 that was made in Gamba, Italy. What a disappointing piece of junk, that was a jam-a-matic. Sold or traded it in.

Wish I had the WWII .32 !

I gotta say it....I have recently shot all kinds of modern handguns in many calibers. Learned to love and even respect a Glock 26 and other modern guns. A Beretta Px4 SC is my daily main carry.

Then I pick up my Colt Pocket Hammerless built in 1924/1919/1918 and run a hundred rounds of .32 thru it and remember what ergonomics and functionality really are. Some of those old .32's were possibly some of the finest pistols ever built and some of the Mausers and Walthers and old Beretta's positively shine in .32/7.65mm. I find the Old School guns built before I was alive to have something I can't put my finger on - something modern guns have left behind. They are not "better" just designed and tuned to be "alive" in the hand as modern guns have yet to match.

For me. How Maudlin.
