I noticed that lots of you use CCI #41 small rifle primers. Have any of you tried using them in 9mm pistol? Are they too hard? I may try a few to see what happens. It would be nice not to have to stock small pistol primers.

I would imagine you are likely to get light strikes.

The only time I use rifle primers in handgun rounds are 44 mag 45 Colt, etc. that are used in lever action carbines.

CCI-400 primers will work in small pistol cartridges but the #41 is going to be to hard plus the #41 is a hot Mag primers so your normal pistol load will have to be reduced greatly.

Back in the 80s I managed to bring back a couple cases of 9mm ammo that turned out to be hot sub-gun ammo with super hard primers. The hard primers did not lend themselevs to working in auto pistols. I had a failure to fire rate of 10 to 20% .

Thanks for the info. I guess I will have to stock both. I was just dreaming.

Never hurts to try. I've used many tens of thousands of Winchester small rifle primers in major 38 Super +P+ loads because they are less prone to flow at high pressures. But that ammo was fired in 1911-based pistols with very positive ignition systems.

Most of the regular SR primers are the same as their SPM counterparts, like the Rem 6 1/2 SR and 5 1/2 SPM is the same primer, and the CCI-400 SR and CCI-550 SPM are the same exact primer with the same cup and same type & amount of flash powder which is why we don't recommend them for use in an AR(or any high pressure rifle round) and why the work so well in some pistol rounds.

Ditto here.

I've run both WSR (winchester small rifle) and Wolf 223 (the Ruski equivalent to CCI #41) in 9mm cases just to see if they'll light. A 1911 will pop them every time (as we'd expect, since an odd caliber for the 1911 was/is the 9x23 Winchester, a pistol round that operates at near-rifle pressures and requires small rifle primers) but forget about it with a Glock. The striker-fired gun would rarely light a rifle primer.

I chalked it up to, "sounds good but doesn't execute."

I use Wolf small rifle primers (not the .223 specific) or CCI small rifle primers, exclusively, for 9mm reloading. Don't shoot anything but Glocks; never had a light strike.
