I saw the 48 the first time while poking around in my favorite gun shop. Didn't know it existed until then, but it had everything I wanted, thin grip, good barrel length, night sights, and of course expected (and delivered) reliability. It's been my EDC ever since. I too think of it as a thin 19, and the loaded weight doesn't drag. Very good entry in the Glock lineup. Waiting on my set of S15 mags from Shield arms.
