I've never minded Glocks, functionally or aesthetically. I'm also of the school that proper training is more important than a hundred external safeties. With that in mind, I think a Saf-T-Blok is a reasonable option, both financially and realistically.
I also think the website mentioned in the original post is wrong on almost every count; "history of accidental discharges"!??! In all the posts here and from all the personal stories I've heard, Glocks aren't any more likely to accidentally discharge than any other handgun; the bottom line is that the user commits the mistake. And all the "proper training" they suggest you do with their own product would be much, much better spent with the original gun in question, to understand it, become comfortable with it, and thus prevent ANY incidents.
No safety can truly claim to prevent an accident. Almost everyone has forgotten a round in the chamber at one time or another; the difference between those who pull the trigger and those who double- and triple-check is training, discipline, and force of habit. Safeties, external and internal, can make accidents only somewhat less likely. But that likelihood is equally affected by the familiarity and training of the user. If your finger isn't on the trigger, the gun will not fire; this is, of course, the best safety of all.
