I just recently purchased a S&W 99 .40 cal. It was a toss up between that and the Glock 27, and I decided to go with the Smith. It's about the same size as a Glock sub-compact but with more features: adjustable sights, dual slide serrations, ambidextrous mag release, decocker, extra grip insert, loaded round indicator and cocked indicator. Anyone have thoughts on these two pistols?
