Here's a part number for the ammo I am using. Tell me if you think this is improper.
Part NUmber#23604 - SPEER Gold-Dot, 32 Auto 60gr, GDHP
I hope the following can be helpful:
(1) All 7.65 Browning or .32 ACP ammunition is semi-rimmed. There is no such thing as rimless ammunition in this caliber.
(2) Some JHP 7.65 Browning or .32 ACP ammunition (e.g., Speer Gold Dot, Winchester Silver Tip) has a shorter overall length than the normal overall range of length from .94 (min) to .984 (max) inches (by SAAMI specs). [CORRECTION: The SAAMI specs for .32 Auto on the SAAMI website now state that the minimum length is .890. I presume the requirement of .940 min is an older requirement, since it can still be found on the website in the full-length SAAMI specs document, presumably published in 1993.] I believe these shorter cartridges, which were not once common, became common as a result of Seecamp's decision to design their gun around the shorter-length Silver Tip round.
(3) Any 7.65 Browning or .32 ACP ammunition which is shorter than about .940 can rim-lock in any magazine which is designed to allow for full length ammunition. (This means that a lower cartridge in the magazine can slide forward, ahead of a higher cartridge, far enough to prevent the higher cartridge from exiting the magazine.) Some magazines for guns in this caliber are designed to only handle shorter length cartridges (e.g., the Seecamp). Others are designed for the longer length rounds (e.g., Walther PP and PPK, Kel-Tec).
(4) There are three ways to avoid rim-lock if you own a .32 ACP gun with a magazine designed for full-length cartridges but you want to carry hollow points:
(a) You can install a spacer in the magazine (called a "flyer wire") which makes the magazine handle only the shorter-length rounds. (I believe this fix is available usually only for the Kel-Tec P32 magazine. It effectively transforms the magazine into a short-length-hollow-point-only magazine.)
(b) You can keep a short-length hollow point in the chamber (and you can also keep a short-length hollow point as the highest round in the magazine if you like, since rimlock is caused by a short-length, lower round sliding ahead of a higher round of whatever length), while keeping full-length rounds for all the other, lower rounds in the magazines.
(c) You can simply use hollow point ammunition which is long enough to avoid rim-lock. I've heard of only a few hollow point offerings which are .940+, including perhaps (I'm not sure however) the (i) Cor-Bon Pow'RBall 55 gr JHP (with a round ball in the nose which supposedly makes the cartridge full-length), the (ii) Magtech Guargian Gold 65 gr JHP, and the (iii) Magtech 71 gr JHP. These latter two do not show good performance from short barrels.
Any of the options above should solve rim-lock. They do not guarantee that your gun will feed hollow points reliably. If you are worried that the flat-ish nose of hollow point ammunition will "snag" on the feed ramp of your gun, but you wish to use hollow points, then your only option, as far as I know, is to use the Cor-Bon Pow'RBall, which has a rounded nose like an FMJ round.
In any case, I think the P32 is a wonderful little gun, the lightest available autoloader in a caliber .32 or higher, if I am not mistaken. And so many of the bigger .32 ACP guns (including the .32 H&R Magnum and .327 revolvers, which shoot .32 ACP) are wonderful shooters. So I hope you find a good solution to your .32 ACP ammo search! There are many great online sources for this round.
