Just noticed 2 different Remington Small Pistol Primers listed in your site. Being not familiar with the Remington Branded SPP, what exactly is the difference between 5-1/2, and 1-1/2 SPPs as listed for Small Pistols. I saw the 2-1/2 is for Large Pistol. I am used to Winchester, Federal, CCI, S&B. What exactly do I need if I am reloading 9mm?
 
My understanding is #1 1/2 are the standard SPP and the #5 1/2 SPP have a thicker primer cup for heavier recoiling rounds like .40 and .357
I've used both for 9mm with no issues in my competition guns.

5 1/2 are small pistol magnum primers. do not use these in 9mm loads but use the 1 1/2.

Hello Ambishooter,

Thank you for bringing this to our attention. We appreciate your interest in our Remington Small Pistol Primers. It's completely understandable that the different designations might be confusing if you're more familiar with other brands like Winchester, Federal, CCI, and S&B.

To clarify, the Remington Small Pistol Primers come in two varieties: the 5-1/2 and the 1-1/2. The 5-1/2 primers are considered magnum primers, which means they are designed for use with high-pressure loads, typically used in magnum pistol cartridges.

However, if you're reloading 9mm ammunition, you should opt for the 1-1/2 Small Pistol Primers. These are the appropriate choice for standard 9mm loads.

You can find the Remington 1-1/2 Small Pistol Primers on our website using the following link: [Remington 1-1/2 Small Pistol Primers - Box of 1000](https://www.gotenda.com/product/remington-1-1-2-small-pistol-primer-box-of-1000/).

We apologize for any confusion caused, and we're in the process of updating the product title to make it clearer that the 5-1/2 primers are intended for magnum applications.

If you have any further questions or need additional assistance, please don't hesitate to reach out.

Best regards,
Team Tenda
 
All clear now. Thank you for the clarification.

Hi Team Tenda, you say Rem 5 1/2 primers are designed for use in high pressure loads in magnum pistol cartridges. On the other hand, 9mm should use 1 1/2 primers. However reloading charts say maximum SAAMI pressure for both .357 magnum and 9mm and even .40S&W is 35,000 psi. In this case, should we use 1 1/2 or 5 1/2 primers?
 
Question for Tenda:

- Can I buy the Tenda-branded paper shooting targets on the website? I can't find them. I received some in an order and want to buy more.
 
not trying to hijack the thread, but anyone know how hard/soft these primers are compared to ginex/campro small pistol? id like to be able to run a lighter mainspring in my shadow but those ginex primers are pretty hard. if these are softer ill definetly order a bunch.
 
I run a TUNED double action revolver. It set off Federal 100 small pistol primers, small dent hit. Now using REM 1 1/2 as they make a bigger dent with the firing pin in double action mode.

PS. Do go to a REMINGTON factory home page and read what the manufacture say is the difference of 1 1/2 or 5 1/2
 
Yes, do read what Remington actually says about the difference in their small pistol primers. Remington does not refer to the 5-1/2 primer as a magnum, and it is misleading to say it is.

The difference between the 1-1/2 and 5-1/2 is the strength to handle pressure. There is no difference between the two in terms of how they ignite. Longer, hotter flames to light big charges of slow-burning powders is what defines a magnum primer, and the 5-1/2 does not have this.

The 1-1/2 is a low-strength cup that is easily ignited by even soft blows. But the cup will deform under high pressures. As such it is great for things like .32 S&W Long, standard .38 Special, and others up to standard 9mm loadings (though I have seen internet reports of 9mm loads resulting in pierced primers, it definitely appears to be the top end of what they will hold up to).

The 5-1/2 is a higher strength cup to withstand pressures of .38 Special +P, major-load 9mm and upwards. But if your gun has the mainsprings to set them off, there is no reason not to use them in lower pressure rounds, too. It's best to think of the 5-1/2 as a standard small pistol primer, and the 1-1/2 as a special purpose primer for guns with weak ignition.

Thanks for the observation. I would like to hear comments from people who have used them in VERY light DA revolvers. I have tried Winchester, CCI, Federal, Fiocchi and Dominion (Russian) small pistol primers in my S&W Model 10 PPC gun and the only ones that reliably and consistently detonate are the Federal SP. Since they are not always available and are usually more expensive than the other brands I would love to have an alternative to go to if I can't get Federals but only if they are going to give me reliable detonation.

Just stick with Federal. Stockpile when you can.

For reloading 9mm, you want Remington 1‑1/2 small pistol primers (standard type). The 5‑1/2 is a magnum-style small pistol primer intended for heavier or higher-pressure loads, which isn’t needed for standard 9mm.
