G26 or a CW9? I'd think CM9 would be more comparable as both are considered "sub compact" class (G26??? seriously??? LOL). CM9 grip length is VERY close to G26, CW9 grip length is comparable with G19.
If concealment is not a key factor in the consideration, G26 would be a better choice.
I have 26, 19, CM and CW in my rotation.. Kahrs are ONLY for Spring / Summer, Glocks are throughout Fall / Winter... and also Spring/Summer whenever attire allows.
