IMO: Keep the Glock, and get one of the mouseguns of your choice. Continually shoot the mouseguns, keep the G26 IWB (or wherever you conceal it), use mousegun for backup.
I think you'll regret selling the G26 later on. Yeah, that is my opinion, and could very well be wrong... but on another forum (ehem... GT) I've seen plenty of posters always talk about "sellers remorse"... where they regretted selling their Glock later on for another pistol.
Worst case scenario: You truly hate the Glock (?), love the mousegun(s) you have... so just sell the Glock then. But beforehand? I'd strongly suggest against this. Just me, though.
Remember: Glock durability, reliability, simplicity, higher capacity, huge aftermarket for replacement and enhancement parts, great forum (
www.GlockTalk.com ), etc. etc. You can also heat up the back of the grip and push it in, if you "hate" the "hump" down there.
Well, to me, guns are tools, and tools which are best when: Simple, reliable, durable, and have higher capacity than the usual others. These're tools to save your life one day, not lawn chairs you need to be comfortable (feely touchy crap
) sitting on for hours in the Sun. When the SHTF, "feel" won't mean squat... especially when a criminal is runnin at you with a knife.
Good luck with whatever you do.
