I'm new to Glocks and just purchased a 26 Gen 4 and am strongly considering getting a 19 Gen 4 in the near future. I've noticed that a lot of holsters seem to be able to fit both guns, even though the slide/barrel and grip length for the 19 is longer than the 26. Are the 19 and 26 identical in other significant dimensions? I'm wondering if one of the more expensive/custom holsters designed for the 19 would also hold the 26 securely. I've been very happy with my Milt Sparks VM2 for my Sig P229 SAS Gen 2, and would consider getting a VM2 sized for the 19 if it could fit both. Any help would be greatly appreciated!
