What Makes a Great IWB Glock 21 SF Holster
A well made, custom Glock 21 SF IWB holster will hold your firearm even if it doesn’t come with a safety strap. The glove-like fit and high natural retention are a result of your new Glock 21 SF holster being molded on the exact replica of your pistol. Thanks to the way your new holster is made, your handgun will not fall out of the holster even if you decide to carry your rig upside down (although we advise you not to carry this way). However, if you want to get as much retention as possible, feel free to choose from our selection of Glock 21 SF IWB holsters equipped with a thumb-break strap.
On the other hand, a perfect fit isn’t the only thing a great holster should deliver. A great Glock 21 SF IWB holster should also come with smooth edges and meticulous stitching. Such features help to protect the holster from abrasion, scratches, wear as well as prevent it from taking any damage should it come in contact with rough surfaces. A great Glock 21 SF IWB holster also comes with a perfect finish, which keeps it protected from dust and moisture. However, in order to ensure longevity and perfect condition of even the best holster, you should regularly take care of your Glock 21 SF IWB holster through proper holster maintenance.
