Glock 26 – Introduced to the market in 1995, the Glock 26 was the first sub-compact Glock pistol introduced into the US, and was commonly called a “Baby Glock”. The G-26 was basically a miniaturized version of the Glock 19 that included all the features and performance of the 19 as well. Most consumers believed the G26 was just a shortened down version of the Glock 19, but that wasn’t accurate. Glock designers had to design the G-26 from the frame up in order to include all the basic G-19 functions, maintain the legendary Glock reputation for reliability, and make it perform as expected. As expected the Glock 26 was a hit worldwide. Although it won’t take the title of being the most popular Glock model, it is considered to in the top 3.
Glock 27 – The success of the Glock 23, chambered in .40 caliber, coupled with the success of the Glock 27, led Glock to release the Glock 27 in 1996. This model was the same size as the Glock 26, but was chambered in .40 caliber. Fans of the G-23 were quick to adopt the Glock 27 as it had all the bells and whistles of the larger G-23 model. Although very popular, the G-27 hasn’t reached the same success found with the Glock 26.
Glock 33 – The moderate success of the .357 Sig caliber, along with consumer input, led Glock to release the Glock 33 in 1997. Chambered for the potent .357 Sig, the G33 was a small package with a serious bite. The G-33 turned out to be least successful of the Baby Glock series in part due to the overall power of the cartridge coming out of such a small handgun and overall less than expected adaption of the .357 Sig caliber.
Each of the gun models listed above (Glock 26, 27, or 33) are basically built on the same frame with the exact same dimensions. As such, a holster designed for any of the 3 will fit the other 2 weapons. In other words, a holster for the Glock 26 will also fit the G-27 and G-33. This is one of the reasons you typically see all 3 models clustered together on holster sites.
The size, weight, and round capacity make any of these models quite popular for CCW and self-defense. All work well in most holster scenarios, with the possible exceptions of pocket carry as some consider the double stack frame and grip a little too wide to effectively carry in a front pocket. The most popular holster style for the Baby glocks seems to be IWB carry, but your mileage may vary.
All the holster models listed below will fit the Glock 26, 27, or 33.
