I try not to get excited because I do not believe they will do a single stack 9mm. It seems with the few clues we have it will be a 45 competition gun & a some sort of 380. Nether does much to excite me.
It will still be a single stack brick with the only trigger glock has and no safety. For a possible pocket sized pistol I guess I would prefer the long DA pull of a hammer fired pistol or revolver or a kahr like trigger vs glocks stiff single action pull. I dont believe they will ever make anything as small as the kahr 380. But then again I dont like the long reset of the kahr triggers either. So Im never satisfied...
I love my glocks but the company does not seem to adapt quickly to what the consumer wants unless the consumer is law enforcement. It really annoys me. That is one thing I like about springfield XD, XDM, XDS.
They should have come out with the single 9mm last year to compete with the xds & Sheild. I would guess they will come out with one in a few years.
