Anyone know why they use small pistol primers in the 45 ACP,
please share.

it was a tree hugger attempt to lower the amount of lead in the environment
the blast pressure waves produced by detonation of both lead styphnate and diazodinitrophenol (DDNP) based firearms primers measured with a high-speed pressure transducer located at the muzzle of a rifle (without powder or bullet). These primer blast waves emerging from the muzzle have a pressure-time profile resembling free field blast pressure waves. The lead based primers in this study had peak blast pressure variations (standard deviations from the mean) of 5.0-11.3%. In contrast, lead-free DDNP-based primers had standard deviations of the peak blast pressure of 8.2-25.0%. Combined with smaller blast waves, these large variations in peak blast pressure led to delayed ignition and failure to fire in brief field tests.
LOL, did you get all of that?

not really???
Th small primers are more better for we humans.
Although I'm sure it has happened somewhere, I've never heard of anyone killed by a primer...large or small.
Kill us deader with more lead content in the larger primers. Lead based primer explosive because it's a more predictable, consistent ignition source.
Smaller primers due to man's attempt at reducing the amount of lead discharge with each 45 to satisfy the (probably Kalifornicated) environ(mental)ists.
Oh, but I'm shooting cast lead slugs so fugit. Buwhawhawhawha!

Friend worked at a place in Eastern WA where they filled military primers. The cups for the very large shells were hand filled in a room called the "boom tomb". As I heard, they kept it somewhere close to zero Farenheit to increase the stability of the primer mix.
The non-toxic primers are small. The pocket is small. Put a small primer in it and charge it. The only problem with them is if you don't look for them and try to shove a large primer in them on a progressive.
IIRC the slurry mix process is still done by hand.
I use a small rifle primer with them and I see little to no difference between them and large primer brass.
