Shield 1 - Still viable! PPS, not so much. Painful to shoot with that crappy checkering, and you can't put a sleeve on it since you have to take the backstrap off of it to disassemble. That is so backward! (Tried the PPS before the Shield was available. No likey!)All shields are sh*t.
That being said ... why would a gen 1 or 2 be obsolete?
Until last week I was still carrying a PPS M1. It still shoots fine, shoots all modern ammo and can kill someone. What is so obsolete about it?
What you are trying to describe is not obsolete.
