The HK VP9, especially with it's slide charging handles make racking the slide quite a bit easier than is normally the case for a semi-automatic pistol. Another potential consideration would be a Walther P5; although they're out of production, and expensive (and they never were inexpensive), they are still available from Earl's (see www.carlwalther.com); their dual receiver-mounted recoil springs make for a lighter slide reciprocation, and the ergos and sights are decent. Definitely an elder hipster gun, though.
