I'm in the same boat trying to make that choice, notice a lot of M&P fans on this forum, kind of refreshing for a change. I'm a fairly new shooter and looking for a range gun for USPSA and steel matches. Really like the feel of the M&P 9 Pro and have been leaning that way but the G17 could be used right away in matches (I could borrow mag pouches, holster and extra mags). Never been a Glock fan but have finally gotten where I can shoot my instructors G17 gen3 fairly well and think the gen 4 would perform even better for me with the new grip design. Although my instructor and several other students are big CZ fans and steadily pushing it, I'm just not ready to spend that much on a tricked out CZ right now. Haven't been able to find either one locally but had one dealer tell me he'd have a Pro9 last week and could get a G17 overnight, I said order both and I'd buy one of them. Well so far neither has come in, not the first time a dealer said he could get whatever I want then not deliver. :angry:
M&P9 Pro-
Feels great, haven't actually shot one yet
Gun and mags hard to find
G17 g4-
Feels great, haven't actually shot one yet
also kind of hard to find right now
mags cheap and available
could use it in matches right away (with borrowed extra mags and holster)
cheaper but I'd probably want trigger work done soon
Decisions, decisions...
