My carry $.02;
Currently, HK P7 and sometimes the wife's PPS. Also have a 642 revolver with CT grips to just throw in the pocket. I need to find a better holster for the P7. Currently I have the Galco PPS IWB, which works pretty well. Of the many I have tried it keeps the most of the grip exposed so you can grab enough to get a decent grip and activate the squeeze cocker. I do need to get something designed just for the HK P7, probably either a Kramer or a Sparks VMII. Can't beat the size, weight, and especially thinness of the PPS.
Guns a have carried CCW in the past;
CZ P01. Great gun though just a tad on the large size. Good ammo capacity, really reliable, shoots good, just replaced it wih the HK P7.
PX4 Storm. Neat little gun though needed to really move the sights when I first got it. Didn't like the safety and the pointy-ends, it always bit my hand when I racked the slide. Also, with the limited slide real estate. Too easy to put the gun on safe when racking the slide. Too much sharp stuff on the slide and it is so short, for me it is just not very ergonomic.
Sig P239. Great gun though a bit heavy. Shoots ultra good. Wife didn't like the long DA pull, got rid of it to get either a DAK model, or one I could convert to SRT. Never got around to getting a new one because the P7 came along.
Sig P229. Good gun though like all Sigs, heavy, big, and especially thick. Face it, Sigs are bricks.
Kimber Pro TLE II. A bit big, and I just did not have enough experience wi 1911s to be really comfortable carrying cocked and locked. Really needs a bobtail. Got rid of it to get out of 45 and concentrate on 9mm and 40.
Kahr PM9. Great gun, very affordable. Did not like the trigger. Kahr triggers are perfect examples or everything that is bad about triggers. Creep, grittiness, too long a pull, etc.
