I'm not extremely well versed in other models; but I have shot enough other handguns to appreciate Glocks. Reliability and easy of disassembly/reassembly would be my main reasons. I have owned an S&W snub .38 (my wife has one actually as well), kimber, and have shot many others like springfield Xd, S&W M&P, Beretta, etc. It all comes back to Glock for me. I understand why people like other makes/models, but Glock just seems to be a good fit for me. You have me intrigued to check out the gen 4 now...
