S&B Small pistol Primers

[mtwain56]

I thinking about using a reduced power firing pin spring in a stock G17 with my own reloads with S&B Primers. I'm wondering how they compare in hardness to Federal SPP's.

[TheChewycookie]

In my test S&B primers are decently harder than most primers. They will run with the stock firing pin spring, unsure of any reduced power springs. That said, I don't feel confident in the reliability of a Glock swapping out springs that aren't the recoil spring or connector.

This forum is a great resource. Thank you.

I've had no problems setting off S&B primers in Glocks with a 4.5lb. firing pin spring and factory firing pin.

They are much harder than Federal

I've tried them in my XDM with PR tirgger kit.   I had a lot of problems with them running a competition trigger and light striker spring.  They might be okay with a stock trigger.

I’ve shot 20 k s&b spp. In 2011 all went band. Small rifle not so much

Currently using them in a Glock with a 4# trigger, no issues.

Used tens of thousands in several Sig P320's. Stock striker/spring. No problems.

Used several hundred in a stock Glock 42. No problems.

I long for the days when you could get 1K for $18.99 or whatever it was back when Cabela's had them on sale. 

(It was Cabela's wasn't it? Hazy memory but not that long ago...)

I  have shot thousands of them in my STI open guns and PCC's as well...... every one of them went ... BANG...

When I was using S&B's, I was able to go down to a 4.5lb striker spring in my Glocks.  Any lower and I'd get an occasional FTF.

With my experience, I think S&B is more harder .

Yes, the good old days...I remember I got them the very cheapest at $17.99 when they had some kind of sale, and I had quite some Cabela Club points on my card, so I took them home for free...wish I could get them now for $30/k. Never had an issue with them.

Back in my prod days, I would get a failure once or twice a match in a g34 with a lightened striker and reduced striker spring. 

Had no issues with the factory parts.

Keep in mind that S&B primers need to be seated 0.003"-0.007" deep. S&B old packaging had instructions that stated that you needed to seat them deep.

I had very good luck with them. I only wish I had bought a lot more at 17.99 a thousand.

Don't we all.

Ran over 30K of them. They used to be $18/K, but I put in a 6lb firing pin spring. They are harder.

I use S&B SPP regularly. I was that person who bought a lot more when they were cheap, lol. They're definitely less sensitive than Federal and Winchester primers. In my opinion they're a near perfect replacement for CCI in terms of sensitivity but YMMV.
