I bought my G21 about 4 yrs ago & I carry it, often in a Summer Special IWB holster on the warmer day's & in the colder weather, I use a shoulder holster, As I am awaiting delivery of a new vertical shoulder holster for my G21 from the VEGA holster co. for thoes that do not know, Vega is a premium, holster co based in Italy, & has only one USA distributer, Python Leather co out of Missouri, they carry Vega's full line holsters at a great prices & their leather holster's rival any of the USA made holsters,Just as good if not better than the top USA holster companies.
