The 17 is a joy to shoot, the 19 is virgin gen 3 I may not shoot if I decide I don't need it. The 26 has nice capacity but for me is eclipsed by the ease of carry for the 43...I never use the flat-based mag or the 26 is worthless for my hands...w/ the factory mag finger extension, the 26 rivals the 19 as the glove box gun. So w/ 17, 26, 43, the 19 is just an outlier (but again, highly collectable LOL).
