Well, be aware that a Keltex 32 is NOT a range pistol - I mean, U shoot it periodically, to stay profecient and make sure it still works. But it is not a gun U shoot 200 rounds at the range w/ routinely.
As much as I love My compact P99 (the same size as the Glock 26), I never did have any reliability issues with the Glock 26 I had for 8 years until last Oct. I just was not as accurate w/ that Glock trigger. Had a G17, 19 and 26 over the years - ALWAYS shot low and left w/ it no matter how much I practiced. Now, th Glock 24 I have is fine, but itc omes stock with a lighter trigger. So, I think that is why.
Anyway, if U shoot the Glock well - get it.
It's pretty much rust proof. And, if U do wear away the finish over time w/ holster wear - send the slide in for $45, and Glock will reblacken it. The black coating is just a cover over the tennifer - U won't wear the tennifer itself off. After 7.5 years of carry, I spent the $45 and had it refinished.
The G26 is best with the pinky extensions on the mag - not sure if the one U shot had it or not - the ones I had added no rounds, but gave just a tiny bit more grip than the flat floorplate
