My first Glock, a 34 would f-t-feed quite a bit with light practice ammo. Fine with full power hollow points. A 15 pound recoil spring fixed the problem.
-My 21 had trouble loading the first round from a 10 round mag. It was very hard to get that 10th round in there.
-My 20 had two f-t-fires with Winchester Slivertip ammo. When the new full cap mags came out, I had many f-t-feeds with them. 10 rounders were 100%.
-My 35 had many f-t-feeds and was terribly innaccurate.
-My 17L longslide has been perfect and very accurate, 2,000 rounds or so.
