I sold it for exactly what I'd paid, I did diligently clean it, perhaps the culprit was underpower ammo, or I may have got one that wasn't well cared for.

Generally, over so many guns that have come and gone, I assume it's me first. It's part of learning about a given weapon, its care and feeding, potential failings.

The Desert Eagle I was able to run like a rented mule. While I've never owned one, I've spent many rounds behind the trigger of a Mk23.

The GB is a unique and interesting gun, surely. I prefer the P7, if we can put them in the same class of gas retarded slides.
