Walther P99c, I like it, But?

I bought a P99c about a month ago and like the gun just fine, however, when I break it down to clean it, I just can't help notice how fragile the gun looks compared to my 2 sigs.
I'm talking about inside the polymer frame, the little tiny springs, the ramp etc.
This is my 1st polymer gun, I know that the glock is a pretty reliable and rugged gun, are the internal frame components beefier or similar to the P99.

Sigbear

The recoil spring on the Glock 26 is almost identical to the one in the Walther - The insides are also similiar enough. Do not worry. Don't throw the frame down on the ground and jump on it without a mag in the thing and the slide on the frame, but otherwise, it is durable enough.
