I've only ever contacted customer service a couple times, both times I was pleased. S&W- I bought a used 22A, a pistol that requires a plastic recoil buffer. The buffer was shot out and falling apart. I called S&W and volunteered that the gun was bought used; they mailed me a pack of buffers free anyway. Thumbs up for them. Armscor- I very recently bought a High Standard 1911 with the Armscor stampings on the underside of the dustcover. I emailed an inquiry to Armscor/Rock Island about whether they made it, if they could give me any info on the gun (I submitted the serial #), and whether it was under any sort of warranty. 2 days later I received a reply; warranty is intact, gun was made in 2007, they made it and marketed it through Lipseys, and if I ever had any problems with the gun to please contact them for warranty service. Thumbs up for them too. My brother had a Bersa .380, which was under the seat of his car, when his car caught fire and burned. Bersa replaced the pistol at no cost, through a gun shop we brought it to (which was a Bersa repair center). Thumbs up there too.
