I am 99% sure it's a Ruger, in the P85/P89/P90 vein. Later and more compact models (P94 and later) take the frame all the way up to the front edge of the slide at rest (later adding a Picatinny rail), but the P89 has that kind of front end. Check this out (P89DC) for comparison:

In fact, I think that's it, in stainless.
