This is a factory 8-round magazine for Sig Sauer P210 Legend pistols.
The Sig Sauer P210 is the gun that started it all for Sig Sauer back in 1949—and the Legend is its most uncompromising and immaculate new revision.
For those who’d spare no expense on an heirloom pistol like the P210 Legend, it’s crucial not to skimp on the magazines. Even if it’s not a pistol that you shoot regularly, having a more complete package can drive up its value and desirability.
If you do shoot it regularly, then spare magazines are a must.
