I ordered my MK9 with night sights. I do use mine for front pocket carry although I too think it's a bit heavy (I am seriously thinking about checking out a MP9 for that). It's accurate and reliable. I had a couple instances of failure to go into battery due to dirt/new condition. After putting 100+ rounds through it I never experianced it again, even if dirty (powder residue & pocket lint). I bet my life on it when ever I'm not carrying my G27. If you already own a G27 I suggest getting a Kahr. Perhaps a MP9? Both the Kahr and Glock line of pistols are well engineered and well made. The Kahr's main advantage is that it is thinner. The Glock is shorter (height) and holds more ammo, but is fatter. I'd never sell either one, they both have their uses. If you have a G27 and pick up a MK9/MP9 you will have your CCW bases well covered for most situations. I am able to carry my MK9 so well my Seecamp .32 almost never leaves the vault (note: I am a pretty good sized guy, and I buy my pants not by brand, color, etc etc etc, only by #1 pocket size, #2 leg size [relaxed fit], and also 1"+ bigger in the waist to allow for IWB holsters.
