Rim Lock in.32 acp

You'd probably have better luck trying to find hollow point bullets with the same OAL as the FMJ's, than try and locate a shim.

On a side note. Hollow points as a general rule don't function very well after being fired from short barrels under 3 inches in length. Lately however, ammo manufactures have started developing HP's that will be more effective when fired from these short barreled compact guns. OAL will still be an issue if you are having problems with rim lock.

The PP has a bbl longer than 3". there are no [factory] h.p. rounds with the same OAL as standard FMJ. in fact there are two manufacturers making a FMJ round with a shorter OAL so they will work in a shimmed magazine like the LWS32; Winchester "white box" and Buffalo Bore.

do you mean most hollow point ammunition is to short to be reliable and the shim is to take up missing space ?

I’m having a hard time imagining this

Here's a pretty good explanation of rim lock and its cause.

Clarification on Rim Lock

A shim?????

Do you have a follower adapted for use with this "shim"?

what shim?

Tenbones has posted a good explanation of the event.


I've never had rim lock with a Walther, or any other blowback .32. They have energetic recoil springs that will often drive an offending round forward. That includes a double stack/double feed CZ.
Locked breech .32s, like the KelTec, can be another matter, with their less robust spring.
Couple thoughts:
-European .32s have a more generous bevel on the extractor groove, which helps discourage rim lock.
-Full disclosure; my .32 are generally fed FMJ reloads.
-Finally, it's not clear what the OP hopes to achieve....380s have seen widespread use, and better ammo. .32s, not so much...the only current makers are Beretta and KelTec, AFAIK.
Just shoot ball, and be careful filling mags correctly.

I am not sure HP ammo does you much good in this round. I shoot nothing but FMJ in both my PP and the CZ-70. I shoot some hollow point in the KelTec P32, but normally when I carry the gun I have it loaded with one HP in the chamber and 7 FMJ rounds behind it. I find this to be the most reliable rapid fire capability with the little P32.

Perhaps the "anti-rim lock shim" that you mentioned in your original post.

There's the problem. How would a standard follower work with a shim in the way?

...and maybe the spring, too.

There is no shim for any Walther mag in 7.65/32ACP. Follower won't function.
My post was about avoiding the "lock" when loading the magazine. Feel one click and load another round. Not tapping!
My one pic was just to show the difference in US & Euro brass in their case grooves. And, what Keltec found to reduce/eliminate their rim lock problem in the other pic. Keltec's kit provides a shorter follower for the shim. This "is" Keltec only, mind you.
Thanks Moon, .....someone is catching my drift. I know Mike is. Not rocket science.
Load...one click.....load another...one click, etc. No tapping. Thumb the rounds out for a test to make sure you got it correct. Try again and range test. Even on WIN Whites Flats or FMJ's.
Test!

Seecamp is the only one who got this right. Almost all HP .32 ammo is shorter than a FMJ round. They made their magazines to only accept the shorter HP rounds focusing on Winchester Silver Tip when they first made their gun.

KelTec used to market a rim lock eliminator for their P32 which I used for a while until I found out I could still get rimlock with some Silver Tip ammo.

I went back to the tried and true method of an HP in the tube and the top round in the magazine. The rest of the rounds in the magazine will be regular FMJ ammo.

You can carefully load a magazine with the shorter HP ammo as described and still have something jar the magazine and cause the upper round to be locked in place by the next lower round (the top round's rim slips behind the next lower round's rim if it is jarred forward). If the next lower round (s) are the longer FMJ, they will not move forward and allow the top HP round to slip it's rim behind the rim of the next lower round.

don't tap the back of the mag to seat rounds like on a 9 or 45.

I've wondered is there any real benefit to doing anything special to a stack of rounds in a fairly heavy recoiling firearm. Seems those rounds are going to get whacked pretty hard as the slide slams back and forth. On a relatively soft recoiling .223 perhaps there is some benefit...I'm really having a hard time seeing those .32, .380, 9mm, .40 and .45 rounds sitting still in the mag under recoil.. Any studies on this?

Why do you need a rim diameter large enough that it is capable of rim lock to begin with? How does a .32 PP function with no extractor? I ask that in regard to how would the pistol function with a lesser diameter rim. Just how much rim does the extractor have to grab? 1917

I asked if there was such a beast. how did you get that I claimed that there was?

Beretta seems to have found the answer in .22lr. .25acp and .32acp... Bobcats and Tomcats haven't any extractors. Larry Seecamp even said his guns didn't need one but he included one anyway just in case.

has there ever been or is there currently an anti-rim lock shim for the Walther PP .32 acp magazines so it can shoot hollow points reliably?

OKAY. The short answer is NO.

WHY JMB included a rim on the .32 is locked away with the secrets of the Shriners and the infield fly rule. It is considered semi-rimmed, so it causes problems not common in other auto calibers.
Some .32s headspace on the rim, others on the casemouth or even the extractor.
Tip barrel Berettas have no extractor, as the gun can be cleared by popping up the barrel. When fired, the spent case pistons out of the breech.

I had a .32 KelTec, and don't remember issues with rimlock, assuming careful loading.
