I wouldn't call the H&K a compact or a full size... Kinda between them. IMO its concealable. About 1/2" shorter overall than the full size rig, otherwise very similar. 15+1 instead of 17+1, the pre molded grips fit great and comes with 2 more sets of side panels and palm grips. Probably keep the shield around for events when there might be a lot of people since its smaller for a more concealable carry, leave the full size at home. Split carry between the H&K and shield depending on what I'm doing. Got another sticky holster with it, it's pretty tight since its new but once it wears in I'm sure it'll be just as comfortable as the one for my Shield. I carry at like 4-5 o clock since I'm fat. And the bigger gun doesn't really feel any different.
Mag release takes time to get used to. Didn't like it at first but it's growing on me, just different than my other two. Now I did like the safety on my shield, was part of my draw and made me feel safer. This one is a double or single action which is pretty cool too. Night sites are also pretty sweet. Excited to shoot it some more this week or next.
