"lug around the Glock" is it that heavy for you? prehaps you need a good blackhawk belt. I gave my aunt my old blackhawk belt with her to use with her lc9 now she says her pants don't feel like they are going to fall down. LOL! Good belt is what you need.
But if you want something smaller I recommend Sig p938. ;-)
Has Taurus really spent more on shipping customers their firearms back to them than actual sales?
