I know you might have seen many many tries of people modelling a Desert Eagle- Pistol (I am sorry for that). This model is not made to get a beauty- render of, but intended as a prop for a character- art that i plan to do. This is my first more or less finsihed model off a blueprint i found on the internet. I would be interested what you guys think about the topology especially in regards to my plans (tried it and it worked already kind of well) to add a subdivision- surface- modifier to get it smooth and control- loops to get the edges to shine 
After you are done hurting my feelings about the topology any tips on how to effectively improve it are appreciated 
For lowpoly model it may be ok, but if you want subd model you must add support edges and always check with modifier on/off.
i actually did this already! Thanks for the feedback.
