Keep them clean, use good ammo, proper technique, and any quality pistol should not jam. Ignore those things and you introduce variables that increase the likelihood of a malfunction. I have a Taurus PT92 that I've owned for over 30 years, I've put at least a couple thousand rounds through it and I can't ever remember having it jam or otherwise malfunction. It shoots as good today as it did when brand new, possibly better. If I practice with it, I clean it, and it's always ready to go when I need it.
