Is it just me, or is there something weird about seeing denfoote's twin glocks in all their black tactical glory on top of my great grandmother's flower table cloth?
Ok, back to the point. I like both, looked at both, looked at the M&P full size, Glock 19, M&P compact, and the G26.
Bought the 19. About to buy the 26, as well.
As I've said before, if for no other reason - 33rd mags
Aside from that, as others have said, longer track record, more accessories, cheaper mags, etc.
HOWEVER, I don't think you can go wrong w/ either one, seriously. BUY THE ONE YOU WANT and/or shoot better. I shot the 19 best out of all of them, so I bought it, knowing I may also want to get the slightly smaller 26 in the future.
I shoot IDPA w/ it, it was my first hand gun as of this spring, have put over 3k rounds through it, no issues, no FTFeed/FtFire, nothing nadda zippo
I have 6 15rd mag for it and 2 33rd mags for it so far. Mine came w/ night sights, a tac light, and 4 of those 6 mags, as well as extended mag and slide controls....
Look up the sizes of each, the M&Pc may feel a little better, and it is a little bigger, the G26 is the smallest of the lot.
One consideration, unless something has changed, the M&P C does have a light rail on it, whereas the 26 does not. One reason I bought the 19, it was in between the M&P and the M&PC, and it had a light rail, and was the best shot for me personally. This first gun neeed to be HD capable, and I wanted night sights and a mounted light. Rather have it and not need it, than need it and not have it, etc.
So, if you want a tac light maybe lean toward the M&Pc, or the G19. However, if the light is not an issue, and it's a toss up, see which one you can get a better deal on, w/ whatever you want on it.
I think no matter which one I bought, I'd probably by at least 1 or two more of the same family. Like the Glock, I believe the M&P has interchangable mags w/ the Compact version. So I would like to have in my case, the G19, and the G26, then whichever one I like the most, I'd buy a second one of those, so for a total of 3 guns in the same family, all using the same mags (larger ones in smaller guns anyway, for back up mags), so I can not only consolidate my round purchases, but mag purchases.
I already have extra 15 rd mags in the house, and in each car, and extra 33rd mags in the house, and my primary vehicle. I can build on that platform, then when I buy additional family versions, I don't have to change a thing, no matter what I'm carrying in the family, I've got extra mags nearby, if need be. And, if for some reason, I'm the one unlucky guy w/ a failure at a bad time, or need to send something off for service down the line, I've got a duplicate and/or another family version, to run the same platform of mags and ammo, as well as keeping it simple for the misses as she comes on board (got her CWP, just need to get her some range time)....
Good luck, let us know what you decide, I don't think you can go wrong.
