Gary C, joev, stellacotton - Welcome one and all to the 642 club. We are happy to have you here with us and look forward to hearing from all of you often.
Gary C - The posts on sight paint are interesting. We have covered it before and we keep getting new ideas and different applications. My thoughts about this are quite different and I am really considering having my front sights milled down to the level of the rear trench (or perhaps removing them completely) from both my 642 and 442. During aimed fire the 158gr Buff Bore I am using takes up most of the front sight anyway and it just obscures the target. This just slows things down on followup rounds as I have to descend down through the target and then back up to the POA. As most of my engagements are point shooting this is really not much of an issue with me, but I think I will be better able to engage in aimed fire with the front sights regulated to lay just under the POI. Another mod to add to the list.
joev - The 642 has a clearcoat over the anodized aluminum frame, This clearcoat will wear with age and can peel under some conditions, and may be harmed by some solvents and cleaners containing ammonia. There is no coating on the stainless steel cylinder and barrel. It is actually quite durable for general use and will last for a very long time under normal conditions. S&W will refinish the clearcoat at no charge at you request if it becomes damaged. I would not let this be a deciding factor in your selection. The 442 has no clearcoat and has a black anodized aluminum frame and blacked carbon steel cylinder and barrel.
DA - After seeing the M29 conversion the other revolving carbine offerings just are not going to make the grade. You have spoiled us

Camjr - On pocket holsters, I use both the Mika and Nemesis. The Mika has a looser fit and allows a full combat grip while still completely holstered, and always stays secured in your pocket during the draw. It has a reinforced mouth that allows easy one handed reholstering (an important consideration). The only drawback is that due to the above mentioned qualities it has no gun retention at all, therefore I like it when wearing heavyweight or tight fitting pants that provide good support. The Nemesis is more of a tighter fitting holster that provides fair gun retention, but will not always stay in your pocket and requires you to "push off" with your trigger finger to draw, this precludes a full combat grip and it is a bit slower than the Mika and is harder to reholster. I do prefer the Nemesis when wearing very light dress pants. If I had to pick one it would be the Mika.
About the 2+2 speedstrip, here is one of the OP's:

stellacotton - That's a good looking EDC set-up you have, add a good quality flashlight and you will be well prepared.
