roknjs... more in answer to your comparison of the G23 to the M&P40C. You
may have already put this question to bed in your mind and if so, perhaps this
can help others who might be comparing these two guns.
The size differences in these guns makes them a good comparison. I'll throw
in the G30 as well, because it is about the same size as well. And all three
of these guns are of very good quality, accurate, reliable.
First off... you probably know this already - you will give up the 14 round
capacity and reduce to 11 round capacity.
Since I have and use the G23, G30 and M&P40C, I can offer a first hand
experience in comparing them in shooting, daily use, and carrying.
Here's why I always choose to carry my G23 over my M&P40C.
14 rounds vs. 11 rounds with such a negligible size and weight difference
that I can't tell which gun I'm carrying. I'll take 14 over 11 for sure.
As for grip security - the .40 cal. is a snappy load to say the least, and for
me, I've discovered something I didn't expect: The M&P grip is more smooth
and form flowing in my hand, which makes the gun shift somewhat more in
the hand while firing! The G23 is less form fitting in the hand, slightly less
"smooth", which actually makes the gun grip more secure in my hand while
firing... less shifting in the hand.
As you can see below, the size difference is truly negligible if you carry IWB
under a garment. The part of the gun most likely to "print" is the REAR of
the bottom of the grip and the minor difference in that part is insignificant in
my ability to conceal either gun equally well.
I took great care to photograph as much straight-down on the guns as possible
so as to avoid the visual distortion that results when not angled straight on.
Using the smaller two-finger hold magazine in the M&P40C reduces the size
somewhat (BUT doesn't make any difference in carry feel OR concealability to me)
and makes the gun even less secure while firing the snappy .40 cal. load. SO I
see no point in using this two-finger hold magazine. It makes no difference
in my ability to conceal the weapon, but does compromise "shootability".
Next thought... if I'm going to carry a gun with 11 round capacity, which would I prefer?
11 rounds of .40 or 11 rounds of .45? As long as the overall size and weight difference
is negligible... I'll take the .45. It's a more enjoyable caliber to shoot and has an
arguable edge in terminal ballistics for self defense. When carrying IWB, I feel no
difference between the M&P40C and the G30 and they are comparable in terms of
So if I have a choice between carrying my M&P40C or my Glock 30 (magnificent
weapon in every respect!) I will always choose the Glock 30.
Again, switching the M&P40 to the TWO-finger magazine reduces the grip length
slightly, but makes the gun more difficult to hold and shoot well. I see no point
in using this magazine:
Now, so I'm not misunderstood - I feel all three of these guns are well made and
excellent guns! No doubt about that. They can all be reliable and plenty accurate!
I also enjoy shooting them all. Any one of them can do the job of personal defense
relatively well. And I wouldn't argue with anyone who might prefer any one of
them for themselves. But, for the reasons I've stated and shown above, my
personal choice is always to carry my G23 or my G30 over my M&P40C.
Hopefully this can help in your consideration of the G23 to the M&P40C. AND, prompt
you to consider the magnificent G30!
