One more time. You have a Glock, so I'm assuming it's acceptable, you can shoot and enjoy it, and carry it.
You can interchange ammunition between the two guns, and, carry hicap mags that will work in the 26.
I've had two jframes, and, sold one. I don't shoot them well.
The design, and my shooting style don't seem to work together. The over 12-15 pound trigger pull on a SW does not lend itself to accurate shooting. Also, the ergometrics of large hands and the small frame don't seem to work well, either. My 360PD autolocked on me during dry firing, another consideration.
The short barrels in 38 cost you about 75-100 fps, in 38 Plus P. 150 in .357 mag.
Don't know how big your hands are.
Glocks for big hands, general rule.
Also, the guys at the range tend to shoot the 26's far better then the heavier calibers, and, very well, much better then snubs.
