It's no secret that I've never liked the Ruger design on the SR9c to limit the slide lock to just that, a stop/lock, and not a release. It's otherwise a perfect gun, hammer or not. Sooo..... as Slingshot said, I started "hacking the gun to death"...I'm not a gunsmith by any stretch of the imagination. Here's what I did.
To make the slide lock a release also, like all my other semi-autos, I filed, carefully, the opposing angles of the slide notch and latch until they were square with each other...not enterlocking. The notch on the slide was angled slightly forward and to the inside. A compound angle of some sort. The angle of the latch face was angled slight backward and to the outside, the opposite compound angle. When I finished I had them as nearly zero square to each other as I could eyeball them. I found that I had to change the slight forward angle on the notch to slight backward for better, smoother release. The angles were still trying to enterlock a little. Now the latch is both a stop, which wasn't effected at all, and a functional release. I left it a little stiff to see if it would "break in" a little. One oberservation is that the metal of the slide is SO hard that I don't think wear will ever be an issue.
I'm not recommending this modification, only sharing my experience. I'm much more pleased with my SR9c now.
