One small point about the Glocks is that although they are often referred to as double action, they are actually single action. Glock calls them "safe action". I think they are a little overrated. It really depends on what you need it for. In most situations the average person is likely to encounter pepper spray would be more useful. Revolvers are nice but have a minimum size. A major consideration is the ammo you want to carry. I wouldn't want anything less than a +P .38. There are technically better cals but you have to consider the cost of target ammo. .357 is nice since you can practice with .38. You can also get revolvers that take auto ammo with half moon clips. So you can get a .45 ACP or .40 SW revolver. Also do you want a grip laser? That would be nice... Also depends how small you want it to be.

This one looks pretty nice: http://www.taurususa.com/products/product-details.cfm?id=253&category=Revolver

I never heard of .17 HMR and .17 HM2 but Taurus makes a bunch of revolvers for that also.
