I recently bought a 27 at my lgs and love everything about it so?...It is simply a Glock 27, not a Gen3, Gen4. I'm just curious about that and can't find any real info. Is mine "less refined" than a 4th generation? Glock.com advertises the Gen 4 as lasting sooo much longer because of the springs, etc. Mine's not going anywhere but it's a nagging question. I paid 509.00 and wonder if the Gen4 would be 579.00 or come with 3 mags. I just dumped my Gen4, 17 because of the rsa issues...random addition. Again I would appreciate some knowledge on this subject and thanks. Hope this is the right forum.
