What gun companies have you dealt with that have given you excellent customer service? Here's mine; Hi-Point - Had a problem with light strikes with my 9mm carbine, called the company and explained my problem. They explained that they knew exactly what the problem was, one of the firing pin springs was broken. Told me it was an easy fix. They said instead of sending my carbine to them, they would send a new spring with a detailed description on how to replace it. I agreed to give it a shot. 3 days later I received a new spring set as well as a new firing pin and a complete step by step description on how to replace. When I followed their instructions they were right on, one of the springs was indeed broken. I was able to replace the springs and firing pin in less than a half hour and it did indeed solve the problem. Three days later I received a call from one of the techs asking if I had any problems with the replacement and was the problem solved. Ruger - Before I purchased my MKIV 22/45 light I knew that once purchased I was going to remove top rail. (was going to use open sights and I felt it would look better without the rail). I called Ruger and explained that I would like to purchase a set of screw plugs once I removed the rail. At no charge and before I even purchased the gun I had the screw plugs mailed to me at no charge. I purchased a used EC9S and I always replace the recoil spring on used purchased firearms. Called Ruger and a replacement was mailed to me at no charge within a few days. After firing my two MKIV's about 3000 rds each, I called Ruger and wanted to purchase new recoil springs for both. I told Ruger that there was nothing wrong with the existing springs, had new springs in about 3 days at no charge. Rock Island Armory - Purchased 9mm 1911 was having a problem with the slide lock not locking slide open after last rd fired. Called RIA and explained the problem, received a new slide lock a few days later, problem solved. EAA - Purchased a used SAR B6P 9mm. One of the metal guides in the frame broke. Sent it back to EAA. A week later received the firearm back repaired and they also included a new recoil spring all at no charge. No charge for repair or for shipping in either direction.
