Well I am not going to be shooting my 3.5 compact anymore for compitiions, Which would you buy for 3 gun/idpa the m&p 9 4.5 or the 5 inch. Both would be the Pro CORE model.

Thoughts?

5" or you can do like me buy the 4.5' and realize you made a mistake and then hope you find someone to buy it from you so you can get the 5". That being said there was a 4.5' on Enos for a very long time that never did sell as for me I lucked out and sold mine. Listen to what you see here
 
I went with the 4.25 barrel and love it. Had an amazing trigger job done on it and never looked back. I use it for IDPA and soon to be 3gun. I came from an XDM 5.25 in .40 for both IDPA/USPA(located in the clasified,lol) The shorter barrel has less weight to it and felt recoil IMO. Quicker out of the holster and so on. There is no wrong answer here, I just enjoy mine.

Good luck and have fun with it.
 
5, I liked shooting my son's 5" XD Tactical better than my 4.5" XDm, at least before I practiced a lot. But I won't tell him because he will want to trade.
 
Well I'm gonna throw gas on everybody's fire.

If you are going with an optic what difference does the barrel length make? The main concern I have is that there is a thread over on enos that have a bunch of people having really crappy accuracy out of the long slide M&Ps. The regular length versions aren't affected with this affliction. One theory is that for some unknown reason the long slide versions prematurely unlock from battery. I find that one hard to believe from S&W especially in the era of ultra high speed photography, I just don't see that one biting S&W in the butt. But I can say definitively that my M&P45 is twice as accurate at 25 yards as my 9Pro. Just something to think about...

The longer slide and added weight will reduce muzzle flip. If you are adding a comp to either barrel, muzzle flip won't matter much on barrel size.

No clue about the concerns with accuracy on the 5" pro models. Is the chamber looser on the pro models to increase reliability? Would that reduce accuray at 25 yds? I know the same load chronograhs much slower out of a 4" glock 19 vs a 3.8" XDm. The slightly longer glock was over 50 FPS slower with the same exact load chronographed minutes appart on the same day.

Dunno about the chambers, but I think they are all on the loose side for reliability. That thread on enos had a bunch of folks brainstorming, measuring, comparing old style vs. new style barrels, loads, sunspot activity and anything else one could dream up trying to find the problem. Some are accurate, some are not. But the ones that are not are too numerous to just discount. I'm thinking it's just that the barrels are "hit or miss" pardon the pun or that the twist rate isn't quite right. The consensus over there was that an aftermarket barrel almost always helps but a long slide Glock or XD usually will still outshoot the bad ones even with the aftermarket barrel. The o/p was talking about going back to Glock just because of this even though he liked everything else about the M&P better. He wasn't the only one either. Again this is only talking about the long slides, the standards are golden. My Pro does decent with J&K 147s, I can hit a USPSA target all day long at 50, but all bets are off with 115 and 124 jacketed. If you can keep them all on a paper plate at 25 you are doing your part.

That chrono data has to be just the two different specific guns. No way .2" is going be be that different.

Thats a bit contradictory.

Go 5" The extra sight radius will make those hard shots cake. (compared to your current rig)
Potato, Patato. Thats how I roll.

I'm not the smartest tool on the belt, but would not less weight(4.25) springing backwards at you create less recoil in the hands than the 5" slide? Either way I rock the shorter.
