I'm looking at adding a 500 to my stable. Namely a 500 Talo Home Defense model # 51236. This model is a standard 500 Purseuder with a matte blue finish. Wondering if anyone has one and if they can chime in. I'm also comparing this model to the new SP 590 # 50778 which is a 590 with the six shot magazine tube. I'm wondering if the 500 would still be lighter than the 590 even though the 590 does NOT have the heavy walled barrel like the a1 version. I already have an a1 and I'm looking for a bit lighter HD gun.
