Hi twyacht,
You're welcome and I'm glad you are going to give the DeSantis Nemesis a try, I think you will be pleasantly surprised.
Regarding the weight issue you mentioned on the PPK, I have found that the weight really isn't a problem if you get a pocket holster that secures the gun within your pocket. By secure I mean that the holster width itself or tackiness of the holster material (the Nemesis for instance) prevents the lateral "swinging" of the rig inside your pocket. While the PCS holster achieves this, it does so by creating a large square inside your pocket and others achieve this with similar bulkiness. The tackiness of the Nemesis fabric achieves this without any bulk, which creates no attention to your pocket or discomfort. Once the holster is secured within the pocket, the shifting that the weight and momentum causes when you walk is eliminated. Once the shifting of the rig is stopped, you'll be surprised how little you will feel the weight, if at all. This is especially true in lighter weight fabric trousers. I can now carry the PPK in a business suit every day with no issues whatsoever.
Now the only thing you need to make sure of is that you have a good belt that keeps your pants from shifting downward. For me it's usually a 1.25 or 1.5 inch Milt Sparks cowhide and sharkskin belt, respectively. I also sometimes switch off to a 1.5 inch Simply Rugged steer hide belt, or a 1.5" Wilderness Instructor's Belt. I also like carrying a Government size 1911 on weekends so these belts do a terrific job. But, having said that, I have found pocket carry really comfortable and convenient as either primary or back up carry. The Nemesis has made it that much easier and comfortable for me, and I like the fact that I ALWAYS have either a snubby or the PPK with me. Next I need a Nemesis for my steel S&W J frame....
Good luck with yours.
