I'll post a couple of photos, but I have a Wilson Combat SIG P320 full size. It is perfect, never had an issue. However, the slide IS NOT optics cut; I couldn't bring myself to send it out and have it milled. So what's the next best thing? I know, buy a whole new slide from SIG, after all they are on sale.
The Slide comes with striker, extractor it's a complete unit. So for $289.99 why not.
I don't have a photo of the 320 by itself, but when you see the photo you will see what I mean. Also, I'll post a photo of the slide I purchased.
