Small pistol primers in 9mm major

[jsoupene]

I have always heard and have used small rifle primers in my 9mm major pistol because of harder cup.  Due to primer shortage what is everyone's opinion on using small pistol primers?

115 Bullets I load srp but 124/125 I use spp.

I have run CCI SPP with zero issues. PF stayed nearly identical as well

I've never run SRPs in 9 major.  Mostly CCI 500s.  Never a problem.  I've been told a couple of times by manufacturer's reps that the priming for both is identical.  The only difference is the harder cup on the SRP. This doesn't apply to LPRs and LPPs.

I've run with no problems small pistol, small rifle, and magnums. They all work fine. 

[S&W686]

I ran Federal Small Rifle Primers in my 9 Major Open Gun for over five years without any issues. 

[dansedgli]

Winchester and Sellor and Belliot SPP have been good in mine. 

 

I use them in everything. 

[iflyskyhigh]

Used SPP with both 115 and 124 gr major loads. In conjunction with Silhouette and now Major Pistol.

 

I switched to SP magnum primers for my major loads, but the difference is negligible. Maybe a touch better accuracy and cleaner burn. Maybe. SDs and ESs were low with all varieties of primers.

I have shot open for ~17 years and only used WSP. No issues.

I prefer SRP, but SPP work just as well. Have heard some SPP can cause breach face erosion, but have not experienced it personally.

Have always used small pistol primers. Currently using ccl 550s.

I thought that was the other way around? 

Rifle primers do it because the cup is too hard and doesnt seal to the case when fired.

I have seen a couple cases of this. 9 Major and 40 Major

i use spp, srp, spm

basically if it goes bang i shoot it out of my open gun

 

except small rifle mags, those are thicker and wont touch off with my hammer spring

[jsoupene]

Thanks everyone for your feedback! This makes me feel a lot more comfortable using spp primers now.

because of the primer shortage i recently used small rifle magnum primers for my 2011 0pen gun and have noticed i have to make sure the primer is seated fully to the bottom or i get light primer strike. I think it is due to the primer cup being harder other than that they all seem  to work the same.

I've started using up Wolf Small Rifle primers in my 9mm Major. Essentially, because I had them on hand, I don't have a small rifle primer caliber, and with the primer shortage now is as good a time as any. 

 

I am getting light strikes through a Glock with a heavier 6lb striker spring. I have not yet tried reseating them with my hand primer tool as part of my quality control. I'm just using them for practice, and Pistol Primers will be for matches.

I can tell you with confidence that Federal AR Match SRP’s will not go bang in my open guns.

 

From day one I have used Federal match and standard SRP’s exclusively in my open rigs with no problem but the AR primers are hard.

Hey you just answered a question I've been trying to figure out for a little while now. Thanks!

Federal SPP eroded breach face in 400 rounds.  Those are to soft.

[Steve RA]

I run SRMPs in 9mm, .45ACP and .223/5.56 and they work well in all.  Tula primers which are unobtainable now but I'm sure any will work.

[funflyr]

SPP work great in my Tanfo.

[Ryan67]

I run whatever small primers I can find aside from the military small rifle which might be too hard. 

[sc68cal]

I had instances where small pistol primers were popping out of the brass and jamming up the gun. I switched to small rifle primers for a couple years, until I had a batch of winchester small rifle primers that a couple wouldn't go off in my gun, so I switched to federal small pistol.

 

I believe that it it was brass that had very loose primer pockets that was the original issue, but I changed who I purchased brass from as well as primer type to the point where there's too many variables to pin anything down and I was just left with superstition.

I use CCI SPP with 100% function in my 9mm Major open guns.
