BudsGunShop.com - Size.

Carl, this is made specifically for the SR9, but the 2 guns are very similar in size. The SR9 is slightly longer and taller, but the Glock is slightly wider. It may be a tight fit width wise, and you may have extra space at the bottom. Just try it out when you get it.
Good luck, stay safe, & have a great day!

Hi Carl and welcome. Yes, when the SR9 was released, Ruger designed it to fit ANY holster made for the Glock. They did this to help customers have the gun readily available to carry with a decent amount of applicable holsters. Cheers and stay safe!
