Before you decide to buy a dedicated game gun, ask yourself what you're trying to accomplish by playing the game.
Personally, it's always been my thought that it's better to come in 5th place with my carry than than 1st place with a gun that serves no purpose other than playing games.
The Pro will give you:
- a longer sight radius
- "competition" sights
- the ability to load your ammo a little weaker if you reload
- the Performance Center sear
Longer sight radius: The benefit most shooters get from a longer sight radius is much less than they think. Put another way, very few shooters will actually end up with a better score at the end of the day because they've got a 5" gun instead of a 4" gun.
Competition sights: Unless the sights on the Pro are exactly what you want, this is wasted money. You're paying a premium for the Pro sights, then you'll spend more money on whatever sights you later put on the gun.
Making Power Factor: Again, it's a legitimate thing but like sight radius,
very few people are actually going to get better results because they used two tenths of a grain less powder in their charge. When Rob Leatham and Dave Sevigny are fighting tooth & nail to beat each other, tiny differences like that might make a difference. When you're trying to beat the guys at your local club ... not so much.
Performance Center sear: There's no denying, the PC sear is a great improvement over the stock one. To me, it's
the reason to buy a Pro. If the better trigger pull alone justifies the increased price over a regular M&P (or whatever other guns you're looking at), go for it. Otherwise ... consider getting a standard M&P (or whatever).
