Well now that you've helped me sort out decockers and manual safeties, how about locking systems?
Should the type of locking system a pistol has be a factor in what pistol you choose? Is it important to know/understand how the locking system functions on a particular pistol? Are certain designs superior to others? (durability, reliability, ingenuity, etc.)
Thanks in advance.

Again, I will bring up the Sig Sauer as a good choice and I'll give reasons why.
The external barrel locking system of the Sig, using a wide ejection port, allows most of the fouling to escape rather than remain contained within the internals of the chamber, feed ramp, and locking recesses of the slide and barrel. The cammed tilting barrel is also a contributer as it reduces fewer parts to the barrel lockup while providing an even keel of consistancy during slide cycle. Having a properly fitted barrel to slide is very important, and the tolerances of fit with the Sigs is flawless to say the least. I've purchased several factory drop in barrels for three of my Sig Sauers and each is fitted so well, daylight cannot be seen between the barrel hood and breech face. I wish this was so easy with the 1911s.

That's great info...and I guess I'm adding to my list of reasons to save up for a Sig...
So does that mean that the locking system that Sig Sauer uses is superior to all others? Is this part of the explanation as to why that can handle calibers such as the .357Sig in smaller guns like the P239? How does the issue of supported vs. unsupported chamber relate to the locking system?

With the SIG's integral feed ramped barrels, this allows for the chambers to fully support the cartridge case, which is an important issue with the high pressure cartridges of the .40 S&W and the 357 sig. While the upper block of the barrel locks into the ejection port of the slide, there is virtually no play in the slide to barrel during the time the primer is ignited, and when the slide is in battery. This is perhaps one good reason why the Sigs are highly noted for their accuracy. There are probably other choices besides the pistols made by SIG; I just happen to find the SIGS to be good primary weapons in a complete package for carry, shooting, with reliable and dependable service. Difficult to find a pistol that offers so much for such a price.

I'm assuming that the locking systems are patented so that other manufacturers can't duplicate them?

flamdrags; Because the Sig incorporates the Browning short recoil tilt barrel design for it's pistols, I'm not sure as to how many others, if any, also uses the same lockup with the wider ejection port as the Sigs. Many, including the Browning Hi-Power, uses the cammed barrel. The SIG lockwork is one design that SIG holds the patent to, although some have copied with class actions which followed.
