gen1 mdl20 issues?

[Streetking]

I bought a mdl 20 gen 1 new, many years ago. it has around 350 rounds shot throught it. should I expect any problems or does anyone have any info about issues.

You can contact Glock inc regarding any safety upgrades if you like........ But the gun is still brand new!

I'm not overly concerned about safety upgrades. Occasionally I read negatives about the unsupported barrel etc. Too much round for the pistol. I also own a gen1 19,26 and a gen3 23. I shoot the 9s often and the 23 a little but the 20 rarely. What strikes me funny is that I never see the 20s in the gun shops.
