Ive been thinking lately about getting some smaller pistol to accompany my CZ85B, one of my options is the Glock 26 so Id like to ask those who are more experienced some questions: 1. Regarding the recoils spring assembly Ive read that it breaks easy so my question is: Is it made of two plastic parts which are somehow joined together or one is plastic and the other is metal? (What about those new recoil spring assemblies for larger Glock of the new generation) 2. Is it possible to carry it in a vest without a holster, in a pocket, as I wear a vest most of the time? 3. Does it lack some durability if we compare it with the larger Glock 17 or Glock 19? Or they last as long and work as reliably? 4. Does it have the same locking block as the Glock 19 or a different one?
