Have you tried any out? My first step was to read reviews then try the ones with the best reviews. I had a friend who could shoot on his own property and he also owned a couple of the ones I was interested in. I rented some others at an LGS that also had a shooting range.
I was mainly interested in concealed carry, specifically pocket carry, so that narrowed my choices a great deal.
The first one was at my LGS. I still have it. So was my second. Most of the others have been on line and sent to a local FFL. I’ve only bought used once (from that friend) and never used from anyplace else, especially from a pawnshop, only because I don’t know how well the previous owner cared for it.
I’ve had to send back several to the manufacturer for servicing, and in every case they fixed the issue without charging me or arguing with me. Excellent customer service. Those were: Springfield Armory, Smith & Wesson and Taurus! I also have several Rugers and have heard they have great customer service as well, but have never used it.
I only wish auto manufacturers and dealers observed the same commitment to service!
