What to do? .. the answer was a deal with Charles P Clement of Liege in Belgium who was making his patented original version of an interesting and accurate 7.65 (.32" ACP) blow-back pistol that had its barrel solid with its frame.
S&W Model 1913 Auto Pistol - AKA Model 35.
- That's A 'Squeeze Safety' In Front of The Grip.
The deal was that Clement and S&W refrained from exporting into each others territories while it licensed S&W manufacturing rights for the Clement design in US.( A similar deal to Colts arrangement with F.N. on the John Moses Browning designs.)
However - somebody at S&W made a 'cock-up' - well really a whole series of cock-ups - so nothing new there then.
The original blow-back Belgian Liege guns used jacketed ammunition - but the experts at S&W who were used to soft lead revolver bullets - decided that jacketed bullets would wear-out their barrels too quickly .. but appreciating that exposed lead noses would cause feeding problems - they developed their own new "Half -Mantle" bullet design for auto pistols that used a cupro-nickel cap or 'jacket' to cover the bullets tip and most of it's nose - while leaving the bearing surface that contacts the bore as exposed lead .. basically this is the reversed feature of a jacketed projectile:
S&W .35" HALF-MANTLE CARTRIDGES -
The Cupro-Nickel "CAP" is Hard To See .. Being 'lead coloured'.
.. Now - don't ask me why - but some internal company expert decided to extend this redesign of the 7.65 mm / .32 acp 'all the way' - and to enlarge the half-mantle bullets diameter by .008" (eight thou.) so that their bullets would not fit into the other makers autos - while standard .32s would still go into and work in the S&W Model 1913 auto.
S&W then declared that their baby's feed was to be called a ".35 Automatic Smith & Wesson Pistol Cartridge." - despite the fact that their bullet diameter was actually .320" - just .008" larger than the ,32 ACP whose bullets generally measure .312" (Don't ask!).

- Then S&W further "enhanced" their proprietary round by giving it less velocity and less power than the standard .32" ACP.
.. And then they failed to offer their 'Half-Mantle' cartridge's "point of difference" design features for any other larger standard calibers (.45 acp?) where it might have proved popular.
Well S&W sold only 8,350 of their 'Model 35' despite its improved & extended life barrels that might last up to twenty times longer than any lands and grooves firing jacketed rounds.

The guns' design was fine .. so much so that after they ceased producing it in 1921 - they then re-introduced it only a few years later then chambered for the standard .32 ACP.
Short Lived .35 'Half-Mantle' Cartridges.
During my several online wanderings researching .32" caliber cartridges and guns - I have come-across 'expert' debate regarding the development of the 32 ACP .
- Most references state that John Moses Browning himself originated the round in 1900 - but some authorities dare argue that Winchester developed the round starting from Brownings supplied prototypes - while making the very first production ammunition - and further, that F.N. and UMC were also involved in subsequent variations.
- My guess is that it is all true - just pick your pet version and be content - as history is a bit of a "moveable feast" - where dates & facts can change over time.
