[quote=“JohnMoss”]Leon - is there any documentation to show that the heavy bullet was made for submachine guns and the lighter 124 grain bullet for pistols? It is not unusual for heavy-bullet loads to be used in pistols equipped with silencers, as the short barrel, with subsonic velocities, can use the heavier bullet to make up for fight-stopping limitions with slow-moving, lighter-weight bullets.
In fact, I have in my collection three slightly different boxes of the 25-round Israelie military type, although all with English language labels (black print on white labels), all three of which say “9mm Ball Carbine 124 gr., Subsonic.” Two of the three boxes, both Lot No. 113-05 (T Z 85) but a different label printing, ) have the cannelure on the bullet despite being shown as “Ball Carbine.” I have no boxes of this type for the 158 grain loading, although I have one "UZI brand box and two slightly different Samson boxes, that show only “9 mm Low Velocity 158 GR. F.M.J.” with no advice anywhere on the boxes that the round is not for pistols (or for that matter, that it is not for SMGs or UZI Carbines). However, the headstamp is the “9mm CARB” marking.
That would tend to suggest that both bullet weights were intended for the Carbine.
Just wondered, as I don’t recall seeing any IMI literature differentiating the weapons intended to be used with the two different bullet weights, and would love to have it for my library.
Fede - to my knowledge, the Carbine, which for legal purposes usually has a 16" barrel, (although I think some made in semi-auto only for police had a 10" barrel), is primarily a commercial civilian firearm. I suspect the proof load described by Johnny was for the Uzi Submachine gun, although I have no precise documentation to that effect. Unfortunately, I have no
Israeli proof-load box of any description.[/quote]
John, I don’t remember where, when, how or why that I have it stuck in my mind the the 124’s were for pistols and the 158’s were for SMG/carbines. And of course you are 100% right about the little 24rnd boxes marked BALL CARBINE 124GR SUBSONIC as I have a photo of that exact box in my photo collection. I will endeavor to purge the faulty info out of my data banks so I will not make that mistake again.
