have a Gen 2 with less than 80 rounds through it. Shoots outstanding ... love it. Been reading about incremental improvements with later generations spawning a few questions for you experts: 1. value of LNIB Glock 22 Gen 2? Flawless with all original materials 2. Cost/benefits of trading up to Gen 3 3. Cost/benefits of trading up to Gen 4 4. Should I consider a 23? Have a new Talo G27 with Ameriglo night sights. If I buy new, I'd want a similar package Have Kahr CM9 & that and the G27 will be my CCWs. The G22 (or 23) will be our high(er) capacity home defense weapon. Appreciate the feedback!
