I’ll update my answer here. Been playing with a 47 the past 2 months. Only have 1,300 rounds on it so far but it’s the move.
Tracks way more consistently than the 17 and 34. They have some kind magic in there.
My favorite was a Gen II Glock 17 frame(NO finger groves and under cut) with a G34 slide. Minus connector and polish job. I always preferred the Glock brand metal night sights. I wish I'd kept that ugly ass gun.
My OD Green G35 with frying pan finish will be one that never leaves my possession. I'll likely be buried with it. lol
