I'm very much a Glock guy and I own a few Gen 4's but lately carrying my Gen 4 G19 has given me some lower back pain. So I switched to carrying a lighter Gen 4 G26 which felt better but still getting back pain after any prolonged period of time. So I Figure its the width of the pistol that is causing this, now I'm looking for a good slim 9mm single stack pistol. Something subcompact that I can find in Massachusetts. Ok NES, what's my best bet?
