Looks like you are not aware that caps means you are screaming.
I had a post all written up but it sounded pretty negative and I was trying to decide whether to post it or not when my computer froze up. Probly a good thing cuz I would not want to hurt anyone's feeling cuz I know they are in short supply these days. ;^) But asking for info on a hundred manufacturers whom make many thousands of guns for a very diverse set of laws in so many countries is asking allot.
I mostly take into consideration where guns are made before I buy these days. I put this list together over the past few months and believe it to be fairly accurate but probly not complete nor perfect.
The guns made in the Czech Republic, Germany, Russia, Slovenia, Sweden, UK, Ukraine and US are of a higher quality in design , materials, fit and finish and have less problems for the most part. They are also easier to get parts for if the need arises.
Guns made in China. Korea, Mexico and a few other places seem to have more problems from day one and often require repair or major adjustment of even new guns for them to operate. They are usually less durable as well.
I am unsure of the Turkish and Spanish made guns at this time.
Many guns are rebadged and sold under reputable company trademarks so it can be difficult at times to know where they really come from.
