Bonus time is here, so I would like to get some opinions on which would be the better pistol. I like them both but can’t decide. I have a Glock Gen 4 17 which has been flawless, but I would like to get a .40 for my next pistol. You’re thought?
Neither are better just different, but why change systems? stick with a G22/23/27/35.
I am pretty happy with my M&P40 and like how it shoots much better than a Gen3 G22. Never had the chance to shoot a Gen4 G22 but I hear they are designed to be better.
Personally I’d get another 9mm Glock, but if you have to add a .40 I’d keep it in the Glock family.
My M&P40 shoots circles around a previously owned G23. It is the most enjoyable shooting 40. platform I’ve owned. Rent both and shoot them side by side, but don’t be surprised if you come home with the M&P40.
Unless you get large quantities of .40 ammo for free and you are wanting to take advantage of that training opportunity, then it makes MUCH more sense to get an identical twin of your current pistol.
If you are actually in need of a .40 pistol, I prefer the M&P40 over the .40 Glocks.
Now I do get “Moderate” quanities of free ammunition for my Gen 3 Glock 22 and I have it “dialed in” to my muscle memory. I don’t care for the M&P but I never have liked S&W autos except for the M-41 and M-52. One thing about the Gen 4 Glocks is the mags are not “interchangable” with the Gen 1, 2 and 3’s. To each his own 
The mags are interchangeable unless you want to swap the mag release button to the other side of the gun. Gen 1,2,3 mags work in a gen4 and they don’t have a small gap at the bottom. Gen 4 mags work in a Gen 3.
Where’d you get that crazy myth?? 
BINGO!

F*CK YA!

Gee, when recently testing gen 4 pistols over thousands of rounds, we used our gen 1, 2, & 3 magazines, along with ones included with the gen 4 pistols we tried; couldn’t tell any differences…
I decided when i bought my first polymer striker fired gun it would be on the same platform. I did alot of research and have gone Glock all the way. I have a 22, 24 and 35 in .40 all are very nice shooting40’s. The 24 and 35 shoot as good as any gun i’ve owned great Glock’s. I do very good with my carry 22 itself but those longslides are my favorites.
I thought we were done with the PistolX vs PistolY vs PistolZ posts?
Anyways…
I’m issued an M&P 40 S&W at work, but I’m currently carring a Glock 22 Gen3 instead (after a long hiatus carrying a 1911). Both are great guns, but the Glock is my preference.
The Glock 22’s have a rep of being problematic. You have to keep in mind that the G22 is one of the most issued guns to LE in the US. You also have to keep in mind that of those guns many do not receive proper maintenance (or any maintenance at all). The larger the sample size the more problematic examples that will exist.
The most frequent G22 Gen3 issue surfaces when a light is affixed to the rail. I’ve owned three Gen3’s G22’s and a Gen4 G22 and have worked on hundreds of G22’s as a department armorer. Most of the guns with WML related issues that I’ve seen have had those issues fixed by upgrading to the newest edition mags and swapping out the recoil sping. Then there are simply some G22 Gen3’s that simply will not work with the light. Most examples I have seen were made in the 2005 to 2007 time frame. There are several agencies that have abandoned the G22 because of this, but the vast majority of G22’s plug along with no problems at all.
I view the G22 similar to how I view a 1911. If you have one that works with a light then it will most likely continue to work just fine with minimal preventative maintenance (changing springs and small parts at regular intervals…2500 rounds or every January for springs).
If the M&P Pro 40 is last years model just cranked out with the PC sear, I’d pass on it. If the M&P is preferred I’d try to find the most recent production - which we’ve read here - would have an updated sear block (MA sear?). Then shoot it smooth or consider other trigger options. I don’t think the PC sears really turned out all that well on the whole for a defense gun.
I checked out a M&P Pro yesterday, overall I liked the way it felt and pointed, even dry fired it a few times. I also checked out a Beretta 92A1 which was nice, however, it just wasn’t for me.
Maybe sticking with the same platform is the best idea, I wouldn’t mind another Gen 4 Glock in 9mm.
So are you recommending another Glock 17, or just staying with 9mm Glocks in general? 
I’d say a G19. We’ve got several 19s and 17s. Although due to uprated dress code in new office, the G26 is proving pretty versatile.
marh415–have you read this thread: https://www.m4carbine.net/showthread.php?t=70567?
Purchase a SECOND pistol identical to the one you already have, so you have one to practice with and another to use as your carry pistol. If you can afford it, buy a THIRD pistol identical to the first two to serve as as back-up or dedicated home defense pistol. You will likely be better off learning to truly master one type of pistol and not switching between different platforms.
I was looking for a new 45 and after reading and taking Docs advice I wound up gettting another glock 19, and have it set up exactly like the first one, minus the sights, Ameriglo pro glos are on the way. That way I can train with the same gun and not worry if anything breaks, I have a spare, plus since we use the glock platform at work, that’s another bonus. I am a firm believer in mastering one platform. It works for me. I am far from the expert though.
