Hello, Already had a used G22, bought a used G23 (Gen 3 w/Rail) this weekend: - Probably 90-95% in box - Night sights - two 15-RD pre-bans - two 10-rd flush fit G23 mag's $575 OTD Range tested the G23 yesterday afternoon, it goes bang and functions flawlessly as I would expect. A little more lively than my G22, but the addition of a Hogue Handall and some more practice should help...results were very satisfactory none-the-less... I find that the 15-RD pre-bans flush fit in my G22 (snap cap cycled fine). My G22 10-rounders function fine in the G23 as did the pre-bans, while both protrude slightly from the grip (obviously the flush fit G23 mag's are too short for my G22). A few questions... 1) Is the same to be expected with the G27? (I know G35 is one-for-one w/G22...my nephew has one...we use our own mag's when we fire each other's for practice) a) Would 10-rd/15-rd G22 mag's function, just protrude from grip? b) Would flush fit G23 mag's function? c) Or does G27 uniquely require G27 mag's? 2) My understanding is that I can drop in a G32 barrel? a) Will I need G32 mag's or will G22/G23 mag's reliably feed .357 Sig? b) If .357 Sig specific mag's are required, would G31 mag' also work? Thanks in advance, N'
