I am ready to purchase my second gun, I now have a P-11 which is great. I really like the way the Glock 19 feels and the magazine capacity. I also like the Glock 26 but would want to put the extended magazine and have the same capacity as the 19. I understand that defeats the 26 main purpose which is to be smaller and concealable. Which model would you experts recommend?
 
In my area a 26 is $479
and the 19 is $499
 
Thanks,
Matt

I looked at the Glock 17 at Gander Mountain and it seemed huge compared to my Kel-Tec P-11. I like the size of the 26 but am not crazy about extended magazine fillers. I like the 15 round capacity of the 19.
 

Most of the people that I know who carry compact Gl"ucks" carry the short mag in the gun and a larger mag as a spare. Sigs operate the same way.

I own a 19, 17, and 26 in 9mm, but carry the 26 more than any of the others (except the 22 I carry on duty).  I can conceal the 26 easily, and for added capacity I use model 19 magazines with a sleeve that lengthens the grip to feel like the 19, without additional barrel/slide lenth to conceal.  I can insert a standard model 26 mag and the pistol fits into the little PDA case I carry it in when I can't wear my shirt untucked for concealment.  I've shot all of them at the range, and the model 26 with the sleeved model 19 magazine shoots as well as any of the others.  With the short model 26 magazine it's a little awkward to hold and shoot at 25 yards, but it still groups well.  There is also a sleeve available for adapting the model 17 mags to a model 26, but I didn't like how long the grip was, and it only added a couple more rounds.
 
G26 + G19 mag with sleeve = 15+1 capacity, more grip to hold, short slide for easy concealment

Get the bigger one!  I have a springfield xd in subcompact and my p3at replaced its carry purpose and I am looking for a full size xd for the range.  Just more fun I think.  More accurate, makes more sense to go bigger at the range.

go for the glock 27, get magazines for the g26 and a storm lake conversion barrel.  then you have the ability to shoot 40 s&w or 9mm
 
all available options with one purchase.
 
YMMV

I like my old 2nd Gen G-19 for home defense and the range.  For a combination CC & Range/HD pistol, the G-26 (with both G-26 & G-19 Mags would work.
One thing I've noticed...  Many of the Holders out there that are listed for the P-11 ALSO fit the G-26, so anyone who owns a P-11 wouldn't Have to buy another set of holsters.  
 
So... Why did I go XD9-sc instead of G-26?  Personal Fit & Comfort.
(as with the G-26...  Any XD9 Mags will fit the XD9-sc)

Good choice IMHO -- very versatile and what I CCW every day (never said I wasn't biased!  ).
 
Now go get the rest of the 9mms, as they all have their own virtues...
