I have a couple Experts and Elites in 9mm. They are really nice pistols. The barrel is fitted to the slide, Match sights, Match Trigger, jet funnel and 18 round mags. These are the best triggers in the HK various models.

As mentioned you have to like the frame and grip as there are no panels to change out.

The pistols are very accurate and with the dual recoil spring they are soft shooters.

HK also has very good customer service as well.

I shot Glocks and Sigs for a while and the HKs have really impressed me.
