My PM9 is a 15 year old bull nose with dead night sights. A faithful companion! I noticed lately that the mag release was kind of mushy so I look at Kahr's site for a new one. It didn't specify if it was polymer or steel so I emailed Kahr to see. Well they asked for my address and sent me a new steel one gratis! Took all of 5 minutes to replace it. Now I'm trying to decide on what to do with the sights!
