I worried about the dust in the pictures, my camera takes such clear pictures. I debated taking new ones. But, after some thought, it's my carry gun. It's on my hip now, and I would rather see a weapon someone uses, than a piece that sits in the safe...
Well I really like the improved grip surface on the Gen 4, and the enlarged mag release might work a little better for me if I had a glove on, while still not being so large as to hit unintentionally. That's at least what I've felt by holding the Gen 4. I can't be for sure because I've yet to fire one myself.
What do you think about the lcp? I have a glock 19 and was looking into getting one of those as well. Its either that or the kel tec pf9. Pocket gun vs compact daily carry. And the holsters....
For your glock you might try an enamal based paint. not sure how it would work on the slide. but that is what they used on signs and it would be weather resistant.
